Problems with MT3G speed/lag

Hello, ive been having some issues with my MT3G over the past few days and ive noticed my phone has been lagging a lot even after rooting, installing latest cyanogen rom and using compcache. here is my setup:
mt3g 32b
cyanogenmod 4.2.11.1
Compcache default settings
lock home app in mem, otherwise i get reloads
i think the problem is that random apps keep turning on by themselves even after i kill them with advanced task manager. phone lags, i check task manager and apps like amazon mp3, market, messaging (i use handcent), locale (i now uninstalled it), settings and other random apps and i never launched any of these apps. so i kill all the apps, the phone runs fine and fast but about 1 min later other random apps load again and i have to rekill them. what gives? ive tried wiping and reinatalling to no avail... why does everyone else seem to have constantly fast mt3g's when i have essentially the same setup?

Seriously, no one?? Come on guys, at least someone has some advice?

have you tried changing your linux swap instead of compcache? Also, have you tried the ram hack?
I'm not sure why you have those things turning on again. I don't have that problem with my mt3g

double post

Thanks for the reply, I don't use linux swap (apps2sd?) considering the phones internal memory is quite a bit. I read about the ram hack but I use the phone for gaming quite a bit so I don't see how I would benefit from that. If linux swap really does make the difference then I guess I have no choice. The only thing that worries me is the sd card wearing down because of it although it doesn't seem to be much of an issue with G1 users or am I wrong?

linux swap is not apps2sd. it gives the phone more virtual memory that it feeds off the memory card to make up for the lack of ram over the 32A. ext is where the apps are stored for apps2sd, but the phone does not need that.
The ram hack only makes 3D gaming suffer. Games like ProjectINF, RoboDefense, Pacman, etc don't suffer from this. Even then, some 3D games still work fine for me, like Toon Warz.
And not the SD card doesn't really go bad, it has on some people, but even then, most sd card come with 5 year warranties. My transcend comes with a lifetime warranty, so you shouldn't worry about it.

Thank you, that cleared up a LOT of my confusion! I read somewhere that Amon_Ra's recovery image will setup linuxswap with one of its commands (partitioning?) or am I mistaken?

it partitions it into the 3 sections. fat32+ext+linux swap. This is what I did. However, this will give you the ext which will transfer all the apps to your sd. you can however, delete your ext if you don't want that using parted in adb. from there, you can use the swapper app and set it to your liking. I use 64mb and 40 swappiness.

Thanks for the help Tazz, linux swap made a difference. There's still a small lag sometimes but much less than before and less frequent. By the way, swapper seems to have been removed from the market for some reason.

Free memory is only 35mb, is that normal

this might be a noob question, and i searched and i cannot find an answer to my question. i have an HTC Magic (32B) and i been installing all types of roms, and they install fine but the problem im facing that they run slow, so i thought i might be running out of RAM memory so i was using TasKiller which shows how much memory i have, and its on average 35 mb of free memory is that normal? i have my SD partitioned with a 96 mb Swap and 512 EXT. how do i increase the free memory because i think thats whats slowing it down. i read somewhere that i need to enable the Swap as it is not enabled by default. can someone help and explain what i need to do, cause everyone else says that their ROMs fly even on G1 and other 32B and mine is slow. I am currently using KingKlik Espresso Rom but i face that issue with all the Roms

What ROM are you currently using?
32B magics don't have the same amount of ram as 32As from what i understand.
type free /proc/meminfo on a terminal and see what it gives you. I hate task manager info's about ram sometimes they don't give a right amount.

32A have a higher RAM, currently i am using KinkKlik espresso ROM but i face this issue with all the ROMs that are not 1.5. i thought when i have the swap file and all that stuff it would expand the RAM space used

Yes, this is normal on a 32B.
Keep in mind Android has a great shared library framework, and allows apps to save state when it moves them out of RAM so they can re-launch later and be back at the same point you left them.

confused over ram/rom/nand & partition size

I'm currently using imilka's Gingerbread Sense nand build (http://forum.xda-developers.com/showthread.php?t=989289).
I was reading: http://forum.xda-developers.com/show...72&postcount=7 trying to understand, with little luck.
I have the TMOUS version of the HD2, with the suggested 350 meg partition. I'm also using APP2SD and have everything possible moved to my SD card (which in my case is around 500 megs in 200 or so programs).
I currently have 162 mb available according to APP2SD.
According to Absolute System, I have 350 MB in system, with 9mb free. If I understand correctly - this is used to hold the o/s (this gingerbread build) PLUS any frameworks I can squeeze into the 9mb, like a circle battery or bootup animation.
Absolute System confirms in data I have 162 mb free.
OSMonitor says I have 48 Megs free btw. And I've un-installed things running in the background that I don't need, but looks like the o/s will just leave other programs open - it looks like it tries to leave about 45-50 free at all times.
SO - why am I getting warning that I am low in memory?? I am now using SPB Shell 3D, which does use 35-40 megs of memory (yes, quite a bit) and want to compensate for it.
Is the 162 remaining used only for app installs?
Is the memory running apps like Shell 3D coming from the 350?
Since I have 160 megs free, can I re-allocate say 25-50 megs more to the o/s for Shell 3D and other apps to use?
If I need to re-partition to a different amount, would I then flash say a 400mb over (cause I tried that initially and remember being laughed at for not following post #1 which asked for 350+). If I do this, I presume I can CWR backup, re-flash partition, then restore..?
Another possibility would be to use the SD card option - can I use this method to say make a 2 gig partition for *all* apps on my sd card, and leave *all* internal memory for Android to run?
Help!

MiniCM9

Ohai ladies and gentlemen , i created this thread to share our performance tweaks of minicm9 , we all use different
I use Nova launcher Prime , Supercharger , Swap 256mb and ES task manager
waiting on yours :d

Why do you use a task manager?
Your phone is supercharged!

Well may not be much but I've finally reached 22 hours with battery life I'm sorry that I can't give the specifics of what i did because I randomly did stuff (supercharge, oc, ram manager, optimizations, tweaking the light sensors) so idk what really gave me almost 1 day battery life with heavy use

New Way : Try Fruit Ninja
I used to play Fruit Ninja (The CHINESE VERSION having pomegranate at the end of the arcade mode) to check every type of performance.
Although i tried Benchmark which does not working properly due to no 3D hardware acceleration.
It shows 130 points for RAM
And goes only to 50 FPS on that spiral test.
But when i checked playing Fruit Ninja ,
Graphic Performance is equal to that of any light GB Rom say STARK Rom etc. without any special tweaks. Even while playing Music.
And when i minimize Fruit Ninja for any thing it does not get off close due to less Ram and on maximizing it do not lags for a while even and go on smoothly.
Also i tried Temple Run and it just running as in GB Rom
And also tried Trial Extreme Winter which is going awesome.
By the way , i am unable to understand that how a tweak can do something, and if they do why they are already not included on the Roms.
I used to format system myself and clear cache and wipe data every time and i disable the services like facebook, widgets, gtalk, gmail etc which starts automatically on any event, using AUTOSTART app , this is enough for me to get good performance.

Here's mine: supercharger, apex launcher, smartassv2 governor with min cpu set to 19 Mhz, max to 600Mz, Only get 12 hours of battery with normal use
Sent from my E15i using XDA

here's mine
ADW Launcher ex latest
KSM - On
Compcache - Off (speeds up a lot! As the os does less work to get data on and off the ram, compression increases ram access time)
Min freq - 19
Max freq - 748
Governor - smartassv2
Undervolt - Off
Full day battery with wifi nearly always connected!
And smooth and fast too...

Apex launcher
600-19 mhz frequency
Smartassv2
Ram manager pro hard multitasking
I got 12 hours max with medium usage.this rom is amazing,but i dont think its usable for daily usage yet.

1day 17 hours
no oc ,smartv2,delete and freeze some app, no undervolt( i found battery drain, dunno why) night sleep using air-plane drop 1%

oc 748.
no supercharger.
apex launcher.
ondemand governor.
1 - 2 days battery life.

To reiterate and expand on my post here:
SD card:
Do NOT make an ext4 partition with swap (and make sure there isn't one)
System setup:
Flash minicm9 and gapps as normal
Remove unwanted applications and services (e.g. for me, Google Talk, FM radio, etc.).
Remove DSP Manager.
If you like the dark ICS theme, you can replace your Contacts.apk, Mms.apk and Email.apk with the ones from here. Flashing doesn't work for me, but you can extract and copy them manually. Do not replace your music.apk.
Flash this zip to get SRS audio support if you want virtual surround when listening to music on earphones (stock player). Similar to what the DSP Manager can do for you, but a lot more lightweight.
Do not 'install a2sd' via console
System configuration:
Set up your autobrightness settings like this
Test your pulse notification light. If it stops flashing after a couple of seconds, go to system/lib/hw via your root file manager and delete/rename lights.shakira.so. Once you reboot, your notification light should work normally.
Disable Google's location service (GPS is okay)
Min CPU: 320MHz (important); Max CPU: ~? (I use 748)
Governor: SMARTASSV2
Disable zRam
Do not enable 'Allow purging of assets'
Do not enable Kernel samepage merging
Surface dithering: Yes
16bit transparency: No|Yes (up to you)
You should now:
Have a for the most part very fluid minicm9 (using Trebuchet). There should be no crashes or instablity, apps will not hang or FC. Memory will feel a little short, but apps should load quickly enough and be incredibly responsive once loaded. Stock browser will choke on low memory, I suggest Opera mobile as an alternative.
This is a very usable state of affairs, but if you want more and have a decent SD card, keep reading:
Performance tweaks:
Do NOT use Supercharger.
Move large apps that are not usually running to SD (e.g. Opera) via Settings»Apps»Move to SD. If this option is greyed out, follow this guide to move them anyway (NB: the command for the ICS platform is set-install-location rather than setInstallLocation).
Install SD-Booster and a SD card speed test of your choice. Adjust the cache until you get an optimal read/write speed (for me, this is at 4096KB) – more is not always better. You can uninstall the speed tester once you're done.
Install Swapper2.
Set swap place to somewhere safe on your SD card (do not use an ext partition)
Set swap size to at least 128M, I recommend 256M.
Set swappiness to 20
Advanced options» tick Recreate swap file and Reformat swap
Enable swap once (may take a bit as it writes the file).
When it says 'Done' open Terminal emulator and type in 'free'. You should now see the available swap (however much you set).
Go to your favourite file explorer and navigate to your swap file/folder. Make a copy of the .swp file
Back in swapper2 go to Advanced options again, and UNtick Recreate swap file & Reformat swap. Once you hit okay, it should say 'Swap file removed, all ok!'. Note that enabling swap will now fail as it can't find the file (bug?)
This is why we made the copy back in your file manager. Open it up and rename the copied swap file to its original filename.
Back in swapper2 (without touching the settings) click 'On'. It should now enable swap just fine. Verify in terminal, and you are done!
Note that to connect your USB storage, you will have to turn off swapper2. As you don't recreate/format swap every time this should be pretty much instantaneous (as long as you remember to do it!)
Your ROM should now still be running every bit as smooth as it was before, BUT you should have a lot more memory to work with, which means apps will no longer reload all the time (I would still suggest to free up apps via home button » swipe if you no longer need them).
Enjoy!

If you've set everything up properly, this should be about what you can expect in performance:

Hello,
how to remove those applications? I don't have "uninstall" button.

Use Titanium Backup or Root Explorer to delete these apps.

Open system/app in a root file manager and delete the .apks you don't use or need.
You can backup your system beforehand if you're concerned about deleting something important.

OK, let me add my experience. Not gonna talk here about self-evident things like remove apps you don´t need, watch what they do in background etc.
Two main things are of concern. Battery life and performance. Now I´m only gonna talk about the latter.
I was one of those unfortunates who used to stare more than 5 secs at the black screen when starting phone, contacts, messages, settings. Tried pretty much every possible combination of governors and CPU freqs to no avail.
Then one single thing that made it better - to some 2-3 secs - was to disable compcache.
The second step I took was experimenting with swap. Now my phone, contacts .. etc open almost INSTANTLY. I´ve got a class 10 32GB SD and I was using ext4 since Slade´s ZP kernel, but without swap. Now it was for the first time I´ve set up a swap in ext4 and for me that solved performance problems perfectly.
So, if you have a DECENT SD card, you may want to give it a try for yourself.
One more thing. If anybody is worried about ext4 speed and/or SD wear - there is a option to disable data journalling on ext4. More on that later if anybody´s interested, or try to google.

Does that solve the problems with ext4 swap?
Because for me (see above) swap works great but as soon as there is an ext4 swap partition/swap file on ext everything comes to a grinding halt.

Amazon tablet optimization. Memory load pressure cured.

Favorite rom -
Faux clock / any kernel tuner -
Enable kms - (setting recommended from Google for low memory device)
Set kms page_to_scan to 100
Set kms sleep_milleseconds to 500
Enable set io scheduler from 2048k - 4096k
Ram memory pro - (this setting help with memory swap when using kms, zram, and swap file combinations)
Enable at boot setting
Set balance tuning for apps and multitasking
Setxperia - (not available in store for tablet/must find and sideload) (setting recommended from Google for low memory device)
Enable zram with 400 MB size (zram have priority before using swap file / that where the magic at) (least used data get page out to zram and then to the page file)
Set swap file to data partition with 200 MB size
Set swappiness set to 100
Create swap. Total swap setting aside should equal to 615 MB
Use zramcc to check if zram/swap working. Swap total size should be 615MB. (reduce swap file size from 400 to 200 to minimize lag when all available swap are used up)
Link2SD - no need for explanation. I used this with a fast flash card to hold my titanium backup and app linkage. This app allow me to have all my apps that I used.
Seeder 2.0 - no need for explanation. This just classic lag free app. Check the entropy resources before and after usage before complaining how old and useless this app is.
Misc -
Unload/uninstall any memory hogged app, like Facebook Messenger (takes up almost 50MB), that like to stay in the system memory permanently. Can't even kill it with task manager. DO NOT USED ANY MEMORY CLEANER OR ADVANCE TASK KILLER. This will cause a swap overload. Let android manage the memory task. Reboot the tablet once all the settings have been applied. The tablet will behave very well and feel like a more expensive tablet.
I have the stock opengapps replace all the core stock rom app. Afterward, I removed any gapp that I do not use.
My Amazon Fire experiences:
My launcher is loaded with widgets and I can pretty much open any application that I used without any freeze or as little lag as possible. I game on this table now and no longer use my phone. Brave frontier and valkyrie crusade.

Update on information
Is all of this information still up to date? Any new additions/tweaks?
Also for some reason, after using zramcc I don't see 615 I only see 415 total.

Err...not really...although much of the guidance is reasonable albeit not optimal IMHO. Check out "L Speed" if seeking a quick tuner with a large following and solid reputation. Tweak one thing at a time and assess benefits before moving to the next item.
