Since Best Buy lowered the price of the Galaxy Tab p1010 (wi-fi only) for a short time following the HP Fire Sale fiasco, a lot of people have purchased this tablet. I did, but not because of the HP Touchpad, but because I wanted a 7" tablet that was fully functional (i.e., GPS, camera, Android Market, etc.) at a decent price. All of my area Best Buys sold out within a week, and most had at least 10 units in stock. Anyway, I knew the limitations of this tablet when I purchased it and I knew it would never be as fast as my old Captivate since it did not have the Hummingbird processor and the SGX540 GPU and no support from Samsung. I did however want to make it as fast and functional as I could, and with the wonderful screen and clean lines, it was one of my favorite picks. It took some time and some testing (and without a firmware backup, a little stressful at times). Here is what I have tried, and luckily with some success. I have compiled this information from other threads. I know this is an older tablet and a lot of this has already been discussed, I just wanted to have one place with all of the tweaks available for the wi-fi only version for others to review and try.
EVERYTHING HERE IS VERY RISKY AND NOT RECOMMENDED FOR AVERAGE USERS. I AM NOT RESPONSIBLE FOR ANY BRICKS THAT MAY OCCUR FROM TRYING ANY OF THESE TWEAKS. I HAVE PERSONALLY TESTED ALL OF THESE TWEAKS ON MY P1010 AND THEY HAVE WORKED WITHOUT FAILURE, BUT THAT DOES NOT MEAN THEY WILL WORK ON YOUR P1010. PLEASE FOLLOW ALL THE DIRECTIONS THAT ARE INCLUDED IN THESE LINKED THREADS AND READ, READ, READ.
Z4 Root: http://forum.xda-developers.com/showthread.php?t=833953
I used Z4 Root to successfully root my tablet. It took two tries, with the first one just hanging up and doing nothing. I held the power button down until it shut off and then restarted it. Tried a second time and had success.
OCLF 2.3: http://forum.xda-developers.com/showthread.php?t=784691
Coming from the Captivate, I remembered that One-Click Lag Fix (OCLF) did wonders for my phone early in the 2.1 days. I installed this app and followed the directions. The first time it failed and I had to do the same thing - hold power button down until it powered off and then restart. On the second try it worked well and I successfully installed the EXT2 files and applied the lag fix. OCLF will let you change the scheduler to NOOP or CFQ (the default). The other schedulers do not appear to be supported. I am currently trying out NOOP, but it seems to have some issues when you have a lot going on in the background. I'll update this post after I try it out for a little bit. One note with OCLF, if you have any apps installed on your external SD Card, you will need to move them back to the phone so OCLF can apply the lagfix.
OK, so getting haptic feedback to work using OCLF - well, it's not without its own problems. You can undo Lagfix 2.0+, reboot and apply Lagfix 1.1, which is the last option under OCLF I think. Now, running 1.1 doesn't really affect anything except it is nearly impossible to undo it. 1.1 somehow deletes your playlogos1 file and when you use OCLF to restore the file, it renames it to playlogosnow. Using Root Explorer, you can rename playlogosnow to playlogos1, but make sure you are renaming the right file (the smaller one). It was a big hassle to get back to the point where I could undo 1.1 and go back to 2.0. 1.1 also deletes your boot-up screen (assume that is the original playlogos1 file), but I returned it to Best Buy the other day after completely returning it back to stock and they didn't give me any problems.
Set CPU (from XDA for registered users): http://forum.xda-developers.com/showthread.php?t=505419
Using SetCPU, I upped the low end to 600mhz and kept the upper end at 1000mhz. I did set a profile for when the screen was off to keep the low end at 300mhz and the upper end at 600mhz to save on battery. I also changed the scaling to ondemand, which seems to make everything a little smoother.
Fugu Tweaks: http://forum.xda-developers.com/showthread.php?t=981125
OK, the Fugu Tweaks are the one mod that I made that I didn't really see any performance improvements. When these became available, most of the devs in the Captivate section applied these tweaks to their 2.2 ROMs and there was some noticeable improvements with several launchers. On the P1010, screen transitions seemed a little smoother with Launcher Pro, but I didn't really see anything different with Go Launcher. I extracted the files from the CWM download and used Root Explorer to replace them under the /system/bin folder (read the OP in the link to make sure you place in the right location). Before replacing them, I made a copy of the original files (renamed to xxxx.copy) so I would have a backup. This is critical since there is no firmware backup for the P1010. When you reboot your tablet, the boot animation will be blank, so don't panic. Also, some apps will not work right with these tweaks - Quadrant is one of them. I don't know why, but it will just go blank and restart. I removed the tweaks and Quadrant worked fine.
Chainfire 3D: http://forum.xda-developers.com/showthread.php?t=1087427
Chainfire 3D is supposed to improve your graphics. I never saw any real improvement when running Quadrant - the spinning earth/moon still looked horrible and choppy. Since most videos play smoothly on the tab without this tweak, I cannot say definitively whether or not this tweak improves performance or not. I did not see any changes in Quadrant or SmartBench 2011. It is a very finicky app and breaks several apps, including several games. I think it has to do with the resolution of the tab being at 1024x600 (or whatever it is) versus being 800x480.
V6 Supercharger scripts - I didn't have a chance to really test these out. I managed to get them installed and running, but altering memory free settings kept breaking some of my news widgets.
Other - you can use SGS Tools from the Market to alter your build.prop settings (you can use any number of programs to do this too, but SGS Tools is easy to use). If you turn on Stagefright (media player only), you can bump up your Quadrant scores to 2100. This doesn't really mean anything as it is an inflated score, but still interesting to see it.
I currently have z4root, OCLF and SetCPU running on my P1010, since those are the ones that seem to have some performance improvements. I get 1600-1700 on Quadrant and about the same scores on SmartBench as the original Droid X (800 something and 1500 something). Nenamark 1 gets me about 21fps. This tab is definitely useable and I only wanted something to surf the web and play some games on the side. NOVA from Gameloft does work on the P1010 and works well (picked it up during the Labor Day sale). Angry Birds plays well, but Angry Birds Rio has some hangups when it first starts (but then again, my Atrix does too sometimes).

If you feel like I have helped you and want to click "Thanks" go ahead and do so. But it doesn't really matter to me. I just wanted to get this information out to others.
Thanks for this post. I have also recently purchased this device at Best Buy.
I used SuperOneClick to root without issue.
I used OCLF and also used the "Change Scheduler" option with recommended settings and tweaks.
I set the dpi to 182 with lcddensity. Setttings didn't initially survive reboot. I don't know how I eventually got them to stick. Just kept hitting apply and rebooting until the setting held. Still sometimes resets to 240. Edited /system/build.prop with ES File Explorer. While I was doing that, I went ahead and changed the default Timezone to my own. Seemed easy enough and the screen is more to my liking.
I attempted to compile my own kernel from Samsung sources. I couldn't get it to flash with Heimdall, though.
I did a roto-backup. Don't know if it will actually work, but I figured better to have a plan than not. http://forum.xda-developers.com/showthread.php?t=850359
Elixir2 gives a lot of interesting info. So does the /proc directory.
One thing I haven't tried on my Tab yet is the V6 Supercharger scripts. Maybe I'll have to try that out soon and see if they'll work on the Tab.. They made a hell of a difference on my phone.
Thanks for the tips. I used to own the P1010
and did the same tweaks with it. It did improve
the tab a lot. But I got issues with the OCLF --
it disables the haptic feedback. Never found a way
around that one.
Anyhow, I already sold my P1010 and bought
the P1000 and never looked back.
I have some new updates to post shortly. I tried out the V6 Supercharger scripts, experimented more with OCLF and SetCPU and found a way to get haptic feedback working. I also had to do another factory reset to get everything working again. I'll try to post here in the next couple of days.
Sorry for not updating the OP. I actually got rid of the Galaxy Tab p1010 and picked up the HTC Flyer for $299. I will make a few edits to the OP but those will be the last edits since I do not have the Tab anymore.
That's too bad... But if you're now happier with the Flyer then so be it
Anyhow, would you mind posting how you got the haptic feedback to work? For the benefit of the P1010 users out there.
Thanks a lot!

Hi wonder if any one can help with my galaxy tab P1010 before I throw it at the wall !! I am trying to put books on from a disk I have. I am useing Calibre to convert them. However as you probably already aware that the device shows up as a portable device and not as a letter on the drive. So I am unable to get the 2 things to connect, I have tried lots of options like changing the driver to a letter, does not work. Also turned off usb debugging, the re installing drivers did not work. Is there any thing else I can do to make it work ? thanks for reading
Hmmmmmm... OCLF doesn't work for mine! Somehow it can't find the playlogos file in the system/bin. Not even a file named playlogosnow. I did a full nandroid backup before I installed OCLF and restored it and I still couldn't find the file in Root Explorer... HELP!!!
BTW, I'm running the KPI version of GB 2.3.6

NEW THREAD HERE
http://forum.xda-developers.com/showthread.php?t=765822
THIS IS NOW AVAILABLE IN EXT2, EXT3, AND EXT4 VARIATES(DOES NOT REQUIRE CUSTOM KERNEL!)
IF YOU ARE USING JH2/JH3 FIRMWARE, READ THIS POST, IT IS VERY VERY VERY IMPORTANT:
http://forum.xda-developers.com/showpost.php?p=7650658&postcount=312
The reason this step is important is that the JH2 firmware is a test build, and as a test build it has GPS logging enabled... this uses an absolutely ludicrous amount of storage space- and the real kicker? It uses the space OUTSIDE of this fix, meaning your phone will encounter low space warnings very quickly if not instantly upon applying the fix!
THIS NOTE IS FOR EVERYONE. THESE FIXES WORK BETTER FROM A FRESH FLASH. THEY *CAN* WORK WITHOUT A CLEAN FLASH BUT REALIZE THAT YOU ARE POTENTIALLY PUTTING YOUR DATA AT RISK!
What this does (Shamelessly stolen from RyanAZ's OP)
Creates a VIRTUAL EXT2 filesystem inside the stock RFS filesystem on the internal SD card, with a 4KB block size. This means that this lag fix creates a buffer between the real filesystem and the android system. This buffer should reduce the amount of disk I/O required for all operations by utilizing EXT2 buffering, as well as not writing file access times to disk, etc.
PROS
Doesn't rely on external SD
Easy to do
Reverse-able
Real, noticeable performance increases outside of Quadrant (Seriously don't pay attention to Quadrant, but if that's what you care about this will make your pants tighter)
CONS
Uses EXT2 file system which is non-journaled and CAN become corrupted, frequent backups are strongly recommended! (2.2 Implements error checking every 30 mounts)
It's also up for debate as to whether this adds extra strain on your internal memory.
1.0 SECTION WILL FOLLOW 2.0 STUFF
AS WITH ANY FIX: READ THE INFO, KNOW WHAT YOU'RE DOING, AND UNDERSTAND POTENTIAL CONSEQUENCES!
LINKS TO GET THE GOODS BELOW!!
The RyanZA version that does EXT2 is Available at the thread linked below
http://forum.xda-developers.com/showthread.php?t=751864
RyanZA has put out an APK version of the fix for people less comfortable doing the update.zip or batch file methods! (This is the V1 lagfix, so for people having issues with the newer fixes this one might work for you!)
TEMPORARILY DOWN UNTIL VERSION 2.3
http://forum.xda-developers.com/showthread.php?t=760571
There is also an update.zip version that does EXT2, EXT3 (1500 Quadrant), or EXT4 (1800 quadrant) versions thanks to Tayutama! I've tested this to work on JH2, and JM5 firmwares! There is also a special version for Captivate JH2 (It also works for JH3) that fixes the GPS Log issues so no need to edit the XML's yourself!

praveer01 threw up a handy writeup for those of you running Unbuntu or any other Linux system:
http://forum.xda-developers.com/showpost.php?p=7671640&postcount=583
READ THE INSTRUCTIONS AND REMEMBER THIS IS *VERY* BETA, NEITHER RYANZA OR MYSELF WILL TAKE RESPONSIBILITY FOR MELTING YOUR DEVICES OR KILLING YOUR DOG IF THIS FAILS. That said, this thread has been very good about helping people who borked their Captivates with 1.0
Here's the reasons you'd want to do this:
Benefits over version 1
1.7GB of application data available, with no data loss. (Up from < 1GB)
e2fsck of the EXT2 partition on each boot. (To scan and fix corruption!)
Correct busybox version included! YES! (Because no one can get it right =P)
/app directory included in the fix for faster application installs.
Mounts instead of symlinks for extra performance as OS does less work (about 100 or so more quadrant).
2.3 Changelog
/dbdata has been removed. This fixes maps issues.
/app-private is now a symlink to /app/app-private. This fixes paid apps issues.
2.2 Changelog
/app-private is included
A second EXT2 partition is created in fast /dbdata storage. /dbdata/databases are moved inside here for increased speed in applications that use it. (System apps mostly, I think)
Proper parameters for e2fsck.
0% space reserved in the EXT2.
EXT2 partition reduced from 1.7GB to 1.5GB to allow more space for captivate users.
Running from a stock install of JH2 I'm currently getting 2300 quadrant scores with ALL AT&T BLOATWARE AND TW ENABLED!
IF YOU'RE NEW TO THIS KIND OF THING, OR ARE WORRIED ABOUT POSSIBLY HAVING TO REFLASH YOUR PHONE, YOU PROBABLY SHOULD WAIT A LITTLE WHILE FOR MORE PEOPLE TO TEST THIS!
___________________________________________________________________________
Found this over in the i9000 forums and tested it myself- I'm getting 2100+ quadrants scores with the stock Captivate kernel and it doesn't hang up on the I/O portion like all the other fixes... in addition you don't require an SDcard for this to work.
Original thread:
http://forum.xda-developers.com/showthread.php?t=748596
One of the folks over there created a one-click lagfixer and it DOES work for the Captivate:
http://forum.xda-developers.com/showthread.php?t=749495
FOR PEOPLE WHO DONT WANT TO READ THE ORIGINAL THREAD
This fix creates a 1GB file formatted in EXT2 and moves all of your apps, data, dbdata into it which DRASTICALLY improves I/O performance. One advisory SHUT YOUR PHONE DOWN PROPERLY, this means no yanking the battery out. Due to it being EXT2, non graceful shutdowns CAN cause corruption.
Edit: No wake up lag either- not sure if that's due to using a non-modded kernel or because the ext2 file is located on the internal memory.
Edit 2: Make *SURE* before attempting this that you have Busybox 1.17.1 or the boot animation script calls won't work!
Link to Busybox 1.17.1
http://forum.xda-developers.com/showpost.php?p=7574130&postcount=229
DO NOT UPGRADE BUSYBOX TO 1.18! 1.18 REMOVES MAKEFS WHICH IS NECESSARY FOR THIS PROCESS
Edit 3: I haven't used the stock Captivate ROM for a while, but this feels quite fast- Also worth noting that this SHOULD work with any ROM- including i9000, I might test that later but I'm enjoying having functioning haptic feedback. 2200 Quadrant with Shootme and market running! Since seeing is believing I've thrown in a screen cap.
Confirmed working with JM5 ROM
IF YOU USE A MAC OR JUST CAN'T GET ADB TO WORK THIS FIX CAN BE PERFORMED WITHOUT A PC- SEE THE POST BELOW:

Ha! it worked thanks dude you should rename this thread with brackets. " [Fix][Lag] Alternative by {author name} - alpha " .. so it can gain more attention. Just we need two more fixes GPS and my attenna issues then i'm good with my captivate.
[edit]omg my phone is flying see this is how my phone should have been out the box it flies!
rebooting from this now. I should not that I had to run the shell script manually because it kept not prompting me for SU...? No biggy though.
Will test, can't post screen from work though.

again, those high quadrant scores mean nothing unless you get no lag in real world testing. Such tests can be done in the following apps: Dolphin HD browser, facebook, twitter, touchdown, k-9 email
All common applications that have serious lag on the SGS. Assuming that this method does fix I/O problems (Especially the I/O quadrant tests), there should be no lag in those apps. Anyone try?

I know you have your reservations about these fixes, and you've been very vocal about your opinions on the matter. I happen to agree with you on most points, but as someone who has tried all of these, I can tell you this doesn't feel like the placebo effect. I'll install DolphinHD and toy with it, but everything I've messed with so far seems much snappier. Feel free to try it yourself, it literally takes less than 5 minutes to install, and is completely reverse able.
Edit: So far with dolphin HD things feel snappy, the only exception is pages absolutely laden with flash lite ads... but that's not really an I/O issue, if you've got any particular web site recommendations I'd be glad to check them out and let you know my mileage
So far so good, I recently erased my phone (130mb lag fix not big enough). And this is working wonderfully so far, dolphon browser HD(my favorite browser) works very fast. So far so good, I'll report back when I've tried it for the whole day.

Thanks! I'll give it a try as I don't like being tied down to 130mb for application storage using the NAND fix.
Basic usage should be snappy:
- opening\closing\switching tabs
- scrolling with the volume buttons
- pinch zooming
- loading multiple pages
On stock, and even mimocan's fix, it would lag horrible to the point of unusability.
The only way to make it run smoothly and quickly was to move all your /data/ to the /dbdata/ on the NAND (but limited to 130mb of app space)
I guess my install question wasnt answered. You said run the .BAT file, do i run it on my pc? And what software on the pc side must i have installed?

Plug it into your pc making sure the USB debugging is on. Download the zip file, extract all of it. Run the Lagfixme.bat and make sure you leave the phone screen on (tap it if low time out) to accept the super user permission request. After that it will finish on it's own. Just reboot the phone by shutting it down. The zip file contains all the necessary files.
Edit: and make sure your phone is rooted / has the drivers installed!

The zip file actually contains a copy of the adb as needed, so other than the drivers to be able to connect via USB Debugging, nada.
All I can say is wow. Definitely not placebo. Certain apps used to take forever to initialize (i.e. Facebook, Market). They now start up almost instantly.
I have not tried any of the other "fixes" because to me they break more than they fix. I don't want to use my external SD in a way that makes it non-swappable and I don't want to be restricted to 130mb for apps. This fix is the best so far. I'm guessing it may not be necessary once we have Froyo (double the RAM) but it does the trick for now.
Seemingly didn't work for me, my Quadrant scores are still sitting at 948. I'm on the stock ROM, and undid the previous speed fix I had.

It was answered:
You need root
Download zip file- unzip it.
Put phone into debug mode and plug in USB
run the included .bat file from the zip file and it will do the rest for you.
It has it's own adb.exe but you might need to install the SDK if you haven't already. That's it though.
After having the Vibrant for a few weeks I simply got fed up with the sluggish UI always lagging, having hiccups and all the latter. I know the phone is better than this (how can my old MyTouch Slide be performing way better?) so I went ahead and rooted.
Before this I would come on XDA and be overwhelmed by the development forums. The terms were so foreign like it's own language. Now I'm getting used to it and can root a Vibrant in under a minute. Very simple procedure.
My first real problem came with the lagfix. At first I could not get RyanZA's fix to work. I thought maybe I did something wrong or my device was faulty. So I tried the update.zip method and it didn't work either. I reset my phone to factory settings, re-rooted, and would come back to the lagfix later.
I came back to the forums today and decided I would try the lagfix again. This time I was more calm and was less overwhelmed thank god. The reason it didn't work the first time was because I didn't have the drivers installed. I went ahead and installed those, as well as Kies (this isn't needed for the lagfix though). After installing the drivers the script worked perfectly. However the script only worked if the phone wasn't mounted, if it was the script would not work, kinda odd but its alright with me lol.
I quickly rebooted and ran quadrant, scored a 2140 baby! Whoooo. There is almost no lag on my phone now. This was my biggest concern was how the phone was so sluggish, now everything is instant and snappy. Really happy with the development of this thing. I feel accomplished now haha.
---
Any how, I'm still very new to the development scene and have some questions.
What is a kernel? How is it different from a rom? Is it good to overclock?
What is ODIN and what does it do? What is ADB? Someone told me to input something in ADB but I don't know what it is.
Also how can you overclock a phone to run at 1.2ghz if the hardware was designed at 1ghz? Can't this make the phone blow up? (no sarcasm)
Now that I've rooted now do I remove the bloatware on the phone? I don't want to install any roms yet until cyanogen or another rom comes out that is easier to install and less harmful to the phone.
Thanks in advance!

It's not odd at all that the fix doesn't work if the memory is mounted. Think of the memory as a cd, it cannot be accessible to 2 machines at the same time. If the memory is mounted/accessible on your pc, that means the phone itself cannot access it and the fix uses that memory so it makes perfect sense for it to be NOT mounted.

A kernel is the core of the OS, it is the main part. Overclocking should not be a problem if you run tests(setcpu burnin or something else)to make sure the phone does not freeze.
What is ODIN and what does it do? What is ADB? Someone told me to input something in ADB but I don't know what it is.
ODIN is a software written by samsung that is used to reflash the firmware/ROM on the phone.
ADB(Android developer bridge)is basically a program which let's you copy and retrieve software onto your phone using the CLI, also it let's you run cli commands on the phone from your computer(much more convenient). ADB is part of the google developers package which can be downloaded from Google fro free.
Also how can you overclock a phone to run at 1.2ghz if the hardware was designed at 1ghz? Can't this make the phone blow up? (no sarcasm)
The phone will not blow up, if the overclocking frequency is higher then what the phone can handle 99 out of 100 times it will just freeze with no permanent damage. A phone's enemy is high heat, not overclocking, eventhough some overclocking causes temperatures to increase.
Now that I've rooted now do I remove the bloatware on the phone? I don't want to install any roms yet until cyanogen or another rom comes out that is easier to install and less harmful to the phone.
Removing bloatware can be done by installing "ASTRO" from the market which will let you uninstall system apps. Some are easy to recognize and some are not. If you are not sure what an app is/does do not remove it.
Thanks in advance!

If ODIN was created by samsung why is it so hard to connect it to your phone?

I downloaded Astro. For some reason I can't even find the .apk file to uninstall the Sims. I tried to uninstall apps like Kindle and Slacker and it wouldn't let me. I thought having superuser permissions would allow me to remove any app from the phone?
Use titanium back up to remove those apps.

Thanks! That app worked! I removed a crap ton of bloatware. Only problem now is that I get a force close error when the phone boots up from an app I removed, how do I regulate which apps open when the phone is turned on?

Hi everyone.
Id like to start a thread where we collect, post and discuss all known individual tweaks and changes that can be made to the Galaxy Tab in order to gain performance and stability.
My experience with the Galaxy Tab has been similar to my latest phone, an HTC HD2. When I got the HD2 about one year ago, I positively hated it... slow, unstable, all sorts of problems, lags, crashes... its the way most of the hardware today is released. One year later, my HD2 has become the most amazing machine I've ever owned. From pushing it 1.6GHz stable, to tweaking registry, XML files, services and making everything work well. I remember not being able to watch smooth video on the HD2 to being able to watch flawlessly 720p content and going from the extreme of detesting the phone to loving it.
It was with the HD2 I discovered Android and fell in love with it. Since I have now two HD2s I have one with an SD ROM version of Gingerbread (that I can dual boot still from Windows Mobile) and a Froyo NAND. I run Android on the HD2 much much much faster and smoother than on the Galaxy Tab, that I also hated when I bought it a few weeks and that am starting to like after getting to know it, a new ROM, apps, etc. Even at 1GHz stock the HD2 with Froyo is vastly faster, smoother, more responsive and better to use. The approach d like to do as far as tweaking the Galaxy Tab is the same as I did for the HD2 with Windows Mobile, that is, install the best/fastest ROM I can, delete and remove all stuff I don't need and then tweak what's left.
The tweaks I've done so far on the Galaxy are simple but have made a huge difference. Id like with this thread to be able to collect individual tweaks and post them all here to share with everyone.
Im using Roto JMI Pre-Rooted Firmware v2 which was the main step after getting rid of the stock Samsung Rom that is nothing but a collection of problems.
The first thing I learned with this Tab is that WHATEVER IS ON YOUR HOME SCREENS THAT MOVES, IS BAD! Forget about having ANY type of apps or widgets that do any type of refresh, including stuff running on the upper task bar if they change icons or the move around… that mean a CPU cycle and refresh each time and there goes the tab's performance and battery life. The same goes for any type of Live Wallpaper. Beautiful but deadly. Never touch them!
- So, after a new ROM, the first thing I did was changing the file system to EXT4. This is the SINGLE BEST THING you can do to radically improve the performance of the Tab. Its extremely easy to do and the step-by-step instructions are as follow:
- Make sure you have an miniSD Card in with plenty of available space (it will be used automatically to backup your system during the conversion process)
- Get p1000-mck-r3-ext4-cwm.tar (the EXT4 Conversion Kernel)
- Connect the Tab in Downloading Mode to your PC via USB, start Odin3 1.7 and load the Kernel (click on the PDA button and select the p1000-mck-r3-ext4-cwm.tar and make sure PDA stays ticked after selecting the file).
- UNTICK Re-Partition check box and make sure the only boxes ticked are:
Auto Reboot
F. Reset Time
The PDA tickbox
- Click start and wait for PASS! (it will show highlighted green or Yellow on Odin)
- Now the Tab will restart and get stuck on the Samsung loading screen. This is normal. Turn it off by holding the power button for 5 seconds.
- Turn on the Tab again on into RECOVERY mode (Press Volume UP and Power On at the same time) and the EXT4 conversion will start automatically. The process will take up to one hour depending on how much stuff you have on your Tab. It took about 10 minutes on mine because I have a fresh install of Roto JMI v2.
- Once finished, click "Reboot System Now" (by pressing the power button).
- The reboot may take a while first time so be patient!
- Done!
- After that, the first tweak I did was to get rid of all my favorite widgets that moved around… net meter, news, weather and all these beautiful things KILL the Tab. Equally I had a CPU meter on the tray refreshing every 2 seconds and it took me a while to figure out that was the reason why every 2 seconds the system would stutter, whether watching a movie or browsing the web. So, out!
- Next was to install SetCPU under the ON DEMAND setting, minimum around 750MHz and maximum 1000MHz (unfortunately only with a custom Kernel you can go higher, currently up to 1.4GHz but not full stable and with lots of issues pending so I don’t recommend it)
- My following step was to get rid of the stock Samsung Homescreen (that is a resource hog and slow as hell) and replace it with a new one. I've tried them all and am making no recommendation here but the one that works for me and is by far the best IMO is LauncherPro. This single app makes using the Tab a whole better experience.
- Next was to disable the USELESS and (resource pig) Gallery and replace it with an app called QuickPic that is blazing fast (actually instant) and simply amazing to browse and view all media on the Tab.
- Next was to greatly improve the poor native GPS reception by replacing high performance files and drivers from the Orange Rom P1000JHKA1 that seems to work on all versions of the Tab, as originally posted here:
http://forum.xda-developers.com/showthread.php?t=922692
- With SystemApp Remover 4.12 I have disabled all system apps and services I don’t need (BE VERY CAREFUL AND DON'T REMOVE ROM APPS YOU WILL NEED). I have actually deleted some from ROM (Root access required of course), this includes useless stuff like STK Service starting every time, most of the Samsung stuff that I really don’t care for and just about all apps I know for sure I will never open a single time. Now, its important to understand if these apps are removed they will be removed PERMANENTLY from ROM so to get the back a hard reset will not be enough, you'll have to fully flash the ROM again. For most system apps I don’t use but am not sure, I use a different option and that is to simply disable them. In my case this includes all Bluetooth stuff (I never use it and even if it's off the Services are still running robbing performance and memory) and apps like the built-in Browser, Email and Messaging that suck and that I replaced with better apps. Its always a safer bet, at least initially to disable the apps you don’t need that uninstall them because at least you can go back and change your mind This is one area where Id like to learn more. There are many background services that I don’t know what they do and if they can be disabled or not. If someone knows what each one does and the safety of getting rid of them OR NOT, it would be great to post it here!
- Them, with Startup Auditor 2.3.2 I have disabled all unnecessary apps that start automatically every time the Tab boots so I don't have excess applications starting up that are not needed. Some I configured to be killed AGAIN if the system tries to restart them later after the boot-up
- Using Task Manager 1.0.7 and letting always run on background, I have configured all apps that I don’t need running to be auto-killed every time the phone goes to stand-by (screen off). This saves me lots of memory and CPU time on apps that I am actually not using.
- Finally, I monitor what is going on with an app called CPU Usage Timeliness Free 1.7.1.0 and use it to see EXACTLY which applications are using CPU cycles and interfering with performance. With it I have found that on my Tab I have an unsolved problem that is using over 100MB of memory and non-stop CPU usage between 15% and 45% of something called SECURITY STORAGE. I have no idea what it does. It can't be disabled and I don’t know where all the activity comes from. If someone know more about this and how to fix it, that will be great. Most of the performance issues I have on my Tab come from this Service that I don’t know how to tame. Surely, we can find a solution.
The system background services is one area where I'd like to know one by one, what each service does and if we need them or not, if it can be tweaked, disabled or deleted. Below is a complete list of the services I have safely disabled so far that have given me great performance boosts and with no negative issues on the system (IN BOLD), and OTHERS I WOULD LIKE TO KNOW MORE ABOUT (not bold). Please note these are background services that start automatically. The changes made to the disabled apps/services is that they are reverted to ON-DEMAND so they all still work perfectly.

Originally with my Tab I was getting Quadrant below 600 on average. Now, its always over 1900. This is not a "little" improvement, this is amazing upgrading. But id like this to be a starting point to learn and share more ways with everyone we can all share on things we can do to make the Tab as good as it was intended to be for everyone
Cheers!
1.4 oc is stable, and doesn't have any issues for alot of users.
all the things you disabled are all the things i use every day lol
never the less, good post, im going to use a couple apps you mentioned.

The first block of disabled items (in bold) from CALENDAR to WORLD CLOCK are disabled start-ups but the apps works as usual. It just frees resources not required on boot till you actually start the application when you want.
The second block from Bluetooth Services to Voice Search are all disabled as I use none of those. Items disabled can be restarted again at any time upon activating them follwing a reboot, while items deleted (like Samsung Apps and STK) are gone forever.
Ive never flashed a ModaCo Kernel and got lots of feedback regarding probelms with 1.4OC. Do you have any issues at all or none? We are using different ROMs... What Quadrant do you get currently?
Cheers
Thank you for your post.
You have solved many of my questions. Also I am User of HD2 and had the same impressions, but now with Android Nand everything was great, also started to love it.
As for GTAB'll make those adjustments you suggested, some will not disable because I use Bluetooth as an example.
Any news please keep posting.
Success!

So far the oc is good, things load a little faster, especially nfs shift. Last run of quadrant was 2300-2400.
Ill try it again later after these optimizations and see how it goes, a member here has gotten 3000.
Having done nothing but root, my tab gets about 1000 quadrant score. I have tried setcpu using on demand and it actuall has made my tab worse. I am very hesitant to flash anything on the tab. It seems very involved and complicated. I have an HD2 as well and have been flashing since Android was on SD. That process is simple. Everything I have read about flashing things to the tab doesn't look that way. I really havent had any issues with my tab as stock other than a bit laggy at times. I would like to hear more about all of this. The oppinions I have read are either do it or don't do it. There are more problem posts after attempting to flash than there are good ones where it worked. I really could care less about a quadrant score to be honest, but I would like to have a faster smoother running tab. I really dont care about making calls on it either. Thats why I have a phone. JMO. I think part of the issue in this thread is that there are Euro and USA version which are completely different and require different roms and such.
I have been reading and lurking in the tab development thread for a while now and am not impressed with any of it yet. Maybe someone could shed some light on things and change my mind.

I agree. The process of flashing the Galaxy is much more dauting than anything on the HD2. I suggest you do the EXT4 file converstion. All you need is follow the step by step I wrote above. It makes a huge difference. As for everything else, I too hold off to do too much flashing. The ROM I use now is great and lighter than stock but your seems to work well so keep it. For me when a ROM is good I just use it. When I bought the HD2 I flashed it 2 times with a custom ROM till i found one that worked for me and kept it for 8 months. But backing up and restoring WinMo is much easier... on Androind its all more complicated if you dont know what you are doing. Disable some start-ups on your unit, convert the file system to EXT4 and make sure you have nothing on your home screen doing a lot of refreshing and your tab will work great

Is everything working 100% on that ROM? I do not want any ROMS that are having problems.
I too am not impressed with anything that us out yet...seems like any ROM process is tedious and complicated.
Glad the thread starter modified his tab to his liking, but what's the point of having it if you need to drastically change everything. I have a rooted DInc and not use any of things......didn't really see a performance gain with set CPU.
I'm going to continue waiting for something more reliable and use my tab the way it was meant to be, with all its hardware and widgets.

My boy,
Only getting my Galaxy tomorrow but looking through threads on my favorite forum.
And guess the first one I happen into... I will follow avidly.
Hi dubie76,
Try an app called OCLF 2.0 on the Market. It is a Lag fix app for the Samsung Galaxy S which also works on the Tab.
https://market.android.com/details?id=com.rc.QuickFixLagFixR2
You have to install EXT2 tools and then install one click lag fix, both are done within the app.
I had this on my Tab before flashed to a custom ROM. The tab was much faster and did not have and lag compared to stock, the Quadrant score was around 1900.
Also you can uninstall the modifications in the app and easily reverse back to stock. The only disadvantage is you will loss about 800mb of internal memory (the 2Gb space), so if you don't have much space left, you will need to uninstall some apps and reinstall them once you applied the lag fix.
P.S. thanks to OP for the SystemApp Remover & Startup Auditor suggestion.
Custom ROMs?
Hi everyone!
Consider this:
The locked GTab (in standby) on an original ROM with a connected to it BT headset wakes up after replying a call from BT and can potentially have anything pressed as being in the bag due to its size...
My point is that there is NO fix for this on XDA therefore why should I expect any significant advancements from a custom ROM if such simple things cannot be fixed on Android.
My personal view is that Android is unfortunatelly not as flexible for adjustments as WinMo (i have HD2 as well with a wonderful custom Artemis ROM).
I've tried two Roto ROMs on my GT and they havent provided any noticeable enhancements in performance to my eye (perhaps some rating went up - I dont care about tech stats). I reverted to stock ROM P1000XWJMI that works as fast for a "regular user".
I am sad to resume my experience with hacking the GT as not worth it: you get serious risk of getting the GT bricked (much more complicated than with WinMo), loose the warranty and are open for instability and sudden incompatibilities with crashes.
On the third custom ROM installation attempt I was stuck on a black screen after powering on (stuck on the bootloader!) and couldnt initiate flash for multiple times. I was shocked and very nervous. Thats when the stock ROM saved my ass and I am not willing the risk of playing around any more with non-firmware ROMs for Android GT.
Regarding the alternative screen lockers available - please do not suggest Screen Suite (the best of the worst) and things like No-Lock (to get rid of the original locker) as they all mess up once in a while (tested) with the default ROM settings and the original core locker.
PS
In my view the best thing we can and should do first of all is to COMPLAIN to SAMSUNG Tech Support and Software Developers (I did twice already).
If every one of us from theese GTab forums would do this they would definitely get faster with resolving issues.

THIS APP HAS BEEN SUPERCEDED BY "Chainfire3D": http://forum.xda-developers.com/showthread.php?t=1087427
It contains all the functionality present in NightMode and more.
.
.
.
.
.

DO NOT INSTALL ON HONEYCOMB (yet)
YOU WILL READ THE ENTIRE POST. YES YOU WILL. EVEN YOU, SUPERCURIO !
About
NightMode itself is an implementation of Jeff Sharkey's excellent power-saving and night-vision-preserving idea for surfaceflinger effects. Really, you should read that link.
The red mode is great in darkness as it does a good job preserving night-vision, for me the power-saving is secondary (power-saving is on OLED screens only)
Unlike Jeff's original article, NightMode is NOT based on surfaceflinger (or other) source modifications, the same effect (more or less) is achieved by using a proxy driver I call CF3D. NightMode serves as the first test of this driver, which will ultimately try to make games run on your device that normally do not.
If you are running CM, you have a similar option already in your settings (which uses the surfaceflinger method).
CF3D driver
The CF3D driver used in the app is a proof-of-concept proxy driver I'm building. It's ultimate purpose is to serve as a compatibility layer and to implement some extra features. Or in normal people English: make stuff work that doesn't, and add some cool.
CF3D is dangerous
The installation of the CF3D driver is not without risk. So far it has worked for everyone who has tried to install it, but you should definitely make a CWM backup before trying!
Successful tests of CF3D
- HTC Hero (not supported by this APK)
- HTC HD2 (MDJ on NAND, Adreno200)
- Samsung Galaxy S (2.3.3, PowerVR SGX540)
- Samsung Galaxy Tab 7" (2.3.3, PowerVR SGX540)
- Samsung Galaxy SII (2.3.3, Mali-400 MP)
- Motorola Atrix 4G (2.2.1 ?, Tegra2)
- Motorola Droid 2 (?, PowerVR SGX530)
- LG Optimus 2X (2.3.4, Tegra2)
More about NightMode !
The featureset is nowhere near what I wanted to release for this beta, but I ran into a lot of snags, and it's simply time to put it out there. For example, what I really wanted is automatic night mode in the dark. However after some testing it became obvious that the light sensors in the phones I used are simply not good enough to accomplish this. So there goes that feature For some reason, they appear to be unable to distinguish between house lighting at night, and pitch black
So the feature set has become really simple: you select which night mode color you want, and whether it should be on or off.
For your convenience, there is also the option to create a shortcut on your home screen to toggle night mode on and off. You can either create it by pressing the button in the app, or: tap-and-hold on the home screen -> shortcuts -> Toggle NightMode.
Requirements
NightMode requires:
- OpenGL ES 2.0 (every 1ghz+ phone has this)
- SuperUser / Root
- Writable /system (it will try to remount system as read/write when needed, but the changes need to stick between reboots)
- S-OFF ??
- Having root access from recovery is a big plus to solve problems if you run into them
Installation
If you have CWM or another recovery-based backup system, make a backup before proceeding !
Install the APK as you would any other. Open the program, and press the "Install" item under the "CF3D driver" heading. This will attempt to install the CF3D driver and reboot your device.
Please make sure you have USB debugging enabled, so you can logcat and potentionally fix problems manually in case of a no-boot.
When installation fails and your device doesn't boot
- If you can achieve root access through ADB shell while booting or in recovery, the fix is usually easy, just execute the /system/lib/cf3d_uninstall.sh script as root.
- Otherwise, if you have CWM, do an advanced restore of the /system partition
- If all else fails, reflash the /system partition or the entire firmware
Uninstallation
Open the app, and select "Uninstall" (if available), then uninstall the APK like you would any other.
Thanks!
Though the app itself may not be very interesting, feedback on devices it does and doesn't work on is most welcome (please include logcats of the boot process), just for the sake of progress with the CF3D proxy driver.

Thanks to the entire reading session that was well worth it I understood it was not at all a Ripoff of the color effects that are in CyanogenMod, not even related.
Actually the concept is super powerful and I'm already flooded by ideas of new stuff possible with this approach.
Fantastic stuff Chainfire.

I really have been waiting for something like this since i got my first android device. Absolutely awesome.
Atrix.
Heehee, updated to v1.1 already... seems I left some debug code in there that disabled PowerVR textures
This sounds really cool . But all the technical stories behind it are completely unclear to me (because I am simply a user, not a maker, so I didn't really delve into this kind of stuff (yet?)).
The thing that matters to me is the battery saving part. Is the amount of battery saving (roughly) the same between these different methods (CF3D/CM7/surfaceflinger)?
And being sufficiently scared by your CF3D is dangerous warnings: did you receive any reports yet from SGS i9000 2.2.1 Users? (Or maybe even more specific, JS8 or Doc rom users, if you think that matters anything.)
I will keep my eye on this, quite interesting .
Tried and tested on Rooted UK Galaxy S2
PDA:XWKE1
PHONE: XXKDJ
CSC:XEUKD1 (XEU)
Install, reboot, Night Mode, all went without a hitch and work as expected.
THIS IS AWESOME (have not tried)

The amount of battery saving should be exactly the same. The battery saving is a property of OLED screens, when not all colors are used. OLED only sends power to pixels that aren't black (for example in red mode, green and blue pixels will remain black, thus not use any power). It has nothing to do with the method used to get there.
There have been no 2.2.1 reports yet, btw.
It works perfectly on my Optimistic 2X
Great work dude!
EDIT: Btw, are you going to release the source at some point?

I find a cool bug lol, i was in yellow mode before i reboot in my red recovery mode, convert my partition in ext 4 with voodoo hack kernel, the boot was in lovely yellow lol. After that u just need to use toggle and all works fine when ur in touchwizz or others home . No incidence for future boot.
Edit : sorry my english is not terrible :-(, hope you understand what i would like to say. See ya
I have been experiencing an issue with the Game Shadowgun I am hoping I may be able to get a little help with. The issue I am experiencing is that the game will pause itself every minute or two. This is actually the only game I have ever had any issues with. The game is fairly intense system wise so I'm thinking it's pausing itself to play catch up, either way it's very annoying, and the game looks sick so have been desperately trying to figure out a way to prevent this. One thing I have been playing around with is Chainfire 3D witch has solved many game related issues on my phone. Unfortunately I still have not had any luck with game. I guess that would go without saying or there would be no need for the post.. Anyhow, If anyone else who purchased the game during the $. 45 sale has had this issue, would greatly appreciate knowing its not just me. Also, any suggestions on a Chainfire 3D configuration or plug-in that would work well with CM7 on the Kindle Would also be greatly appreciated..
I’m using the IngCr3at1on 2/26 build with IntersectRavens 2/22 Kernel.,
I am not Supercharged but had been using Auto-killer with a very mild preset and no Kernel Tweaks. Thought it may have been responsible so have since uninstalled but doing so did not change anything.
Played around with different Governors like Interactive, Ondemand, and my personal favorite Hotplug. I have also tried setting Noop as the scheduler.
With Chainfire I’m basically just starting out with reduce texture quality and a few others but have honestly just been trying the game and then starting back again clean before trying other settings each time so basically starting from scratch with each attempt.
Also tried the VM heap size at both 64 and 48, been at it a few nights now and am on a mission.
Which version of CM7 are you using? Any Super Charge scripts enabled? What setting are you using for your cpu governor? Sorry for all the questions but it will help eliminate the issue. If you've changed a lot of settings in ChainFire you may want to reset everything to default for now.

My bad on the details or lack of, Will expand on the post above.
On another note, just now made another attempt at the Transparent Status Bar. Had the same issue as before but had an idea so went into Titanium, froze my launcher and Status-Bar then defrosted the launcher followed by the Status-Bar and Walla, Transparent Status Bar. Thanks again for taking the time to put that together for me. Sorry got mixed-up in the order of that as I just reproduced it and it worked defrosting the launcher first followed by Status-Bar. Either way its now working. Arge, whats wrong with me today, its Status-Bar followed by Launcher.
Looks like I may have figured it out. Really did not expect this to work but been playing an hour without a pause, beating my previous record of 3 minutes. Read this on another devices thread.
1 install Shadowgun
2 Open and download the extra packages
3 Move the games folder from the Android SDcard directory to the SDcard Root directory
4 Uninstall Shadowgun
5 Set Chainfire with all openGL settings checked except RGBA and Unroll
6 Install and apply NVIDEA plug-in,
7 Reboot into Recovery and wipe caches
8 Reboot and install Shadowgun from the Market or whatever they call it these days but don’t open after installing
9 Move the folder from step 3 back from whence it came so it will not need to be downloaded again
10 Open Shadowgun.
Did not expect this would work but so far so good.
Edit: No go, worked for an hour or so after doing the above but then the following day it was back to constant pausing every 2 or 3 minutes. May try an older Kernel. Having the same issue now with Dead Space and being that I have not read many 3D game complaints I'm guessing its just me.
