I'm just wondering what the general consensus was regarding the speed, the "snappiness" if you wil, of our rooted devices? I'm running the "unofficial" build of Carbon Rom on my HD+ and I think it runs pretty well. Def not as fast as a dedicated tablet but for a glorified e-reader, its not too shabby either.
I do need to be proactive with my usage of the unit of course, but I'm sure most of us here are. What I mean by that is that I do make sure I have as little as possible in terms of startup items (daemons) and run the occasional "fix permissions" or "clear cache"...
I've never tried a different rom besides Carbon, it was the first one I tried and I liked it enough that I kept it. For those that have tried others, do any run faster or smoother then Carbon rom? How is the state of the latest builds of Cyanogen 10.1?
Performance is sporadic. It is like something is in semi sleep mode at random points and the device has to wake up to get going again (this does not happen while using apps). Touch response is fine and the awful stutter (due in part to the constant library syncing) that the stock rom has is gone.
In spite of the lag, still works great. I am running into games that do not work that do on my other three Android devices, but again- we are probably using this device beyond the scope of its intent. The 4470 is a capable chipset, but something that goes beyond the 1080p display bottlenecks the device.
Perhaps the low ram (about 250 is allocated to the gpu) and the 1080p combine to be an issue that occasionally chokes the device- hence the lag. The T700 has a Tegra 3 that also has issues, but the increased the clock for both chipset and gpu to help offset the chipset limitations with 1080p.
Both the 4470 and Tegra 3 work fine with most 1080p video media, but pushing data to that many pixels is a much heavier resource issue.
Honestly I'm struggling with this quite a bit. I have an iPad 3 which is amazingly snappy on everything I throw at it, but I really prefer Android to iOS (I recently switched my handset from an iPhone 5 to a Galaxy S4 also) and the form factor of the HD+. However, I'm getting really frustrated with the intermittent lag on the HD+ with every ROM I've tried. It would almost be better if it lagged all the time because at least then I'd give up on it, but when it's not lagging, it's really an enjoyable device. But then it just starts lagging all of a sudden and I either reboot or go grab the iPad.
I understand that this device is resource constrained on both memory and GPU, but that still doesn't explain to me why it performs so smoothly sometimes and then lags other times until I restart it. I still think that there's some kind of resource leak or other type of bug that causes it to degrade into a bad state over time and that, once identified, will allow this device to be closer to what we're all wanting! Of course, that's also probably hopeful thinking...
My point exactly. The only common issue is the intermittent lag. I also have issues where it will freeze for over a minute and sometimes needs to have the power button held down to shut down and restart.
Becoming more a love hate relationship. Frankly were it not for the lovely display, I would have already returned it. I have the lag and occasional freeze is issues, regardless if a few apps or a lot of apps on the device. There is something apparently funky going on that causes the bottlenecks and occasional freezes.
Added: So far, more love than hate As far as the display, that is why I got the device in the first place, so would have not bought it without it.
I was having to many reboots and lag issues with CM10.1. then I flashed tweaked carbon rom and haven't had any issues at all. I have only had this tablet for about 4 days. This is day 2 with tweaked carbon rom. Love this tablet.
I had a Nook HD that was nearly flawless on CM 10.1. Two weeks ago, once the fire sale was on, I bought this HD+. I'm running CM 10.1 on emmc. I haven't tried Carbon yet! I haven't seen a lag issue but I do get the occasional soft reboot. I use my HD+ mainly for reading, and some light games. The HD is a little smoother, but I like the HD+'s size better. Besides, the display is great for reading. It is fast enough for what I use it for. The HD+ is an amazing deal for the price now. If speed was my ultimate concern, I'd be checking out that new Nexus 7.

I don't have an issue with lag myself. An occasional stutter if I have been using a CPU and memory intensive game and then switch to something else but that is it. Try Carbon it is pretty smooth.

Maybe android 4.3 will improve nook speeds with trim support. But I don't know if it just applies to nexus devices...
http://www.xda-developers.com/android/yet-another-reason-to-update-to-android-4-3-trim-support/
When I first started with my nook hd plus, the tablet was reasonably fast and had little lag. Now after 3-4 weeks it seems to be slowing down and lagging. I'm running the 7/19 cm 10.1 rom. Maybe a newer rom will help out. I haven't tried any other roms.

You guys might want to try lagfix https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix
I ran it and my nook seems to be a bit snappier.
When comparing benchmarks using Androbench https://play.google.com/store/apps/details?id=com.andromeda.androbench2 before and after it showed slightly better results too so it definitely does something.
This does the same thing as 4.3 when it comes to TRIM so its a good test to see what we can expect.

I can attest that this makes a BIG difference! I'd actually stopped using some apps because they now lagged so badly, Flipboard being a key example, but also Chrome (I'd gone back to the original Browser app). Immediately after having this run an fstrim, both of those apps are smooth again! I went ahead and bought the full version for $0.99 so that I can schedule this to run at 3AM every morning. As snargledorf mentions, this will be part of 4.3 so, assuming we do end up with a 4.3 ROM for the HD+, I'll be able to uninstall this app, but in the interim it seems to make a fairly significant difference along with some of the other tweaks I've picked up from the forums (disable zRam completely being a key one, perhaps also limiting the number of running apps to three).
Thanks much for the tip!

I downloaded this zram settings. How are you configuring it? If it makes the Nook HD+ better, I am all for it. So trying to follow some of the things you are doing.
Also I noticed that when I change the background process limit to 3, it changes back to standard limit when I reboot the tablet. Can I select the dont keep activities so it kills the app every time I close out?

I have zRam completely disabled. That definitely helped quite a bit. I haven't seen the background processes setting revert.

Funny, I just bought an iPad 3. With it jailbroken, it's pretty awesome and a lot of the tweaks feel native. I'm still holding onto my Nook HD+, though, for some kind of breakthrough that'll make it perform just as well as my Nexus 7.
Okay, here's how I have CM10.1 (8/1/13 build) on my HD+ configured now and I'm actually quite happy with the resulting experience:
LagFix – I set this to run automatically at 3AM every morning, and it has made the single biggest difference so far IMO.
Settings>Developer Options>Window Animation Scale/Transition Animation Scale/Animator Duration Scale – Either Off or .5x; I use .5x.
Settings>Performance>Processor>CPU Governor – Hotplug or interactive; I use hotplug. Make sure you check Set on boot.
Settings>Performance>I/O Scheduler>I/O Scheduler – Deadline or cfq; I use deadline. Again, make sure you check Set on boot.
Settings>Performance>Memory Management>zRam – Disabled.
Settings>Performance>16bit Transparency – Checked.
Settings>Performance>Surface Improvement – Fix color banding and blur effect.
I also set the LCD Density to 260 DPI since the screen’s physical density is 256 DPI. I use Build Prop Editor to change that setting and therefore have to change it every time I flash a new ROM. I've tried to put it into /data/local.prop and have it survive across flashes, but I haven’t yet had success doing so. Anyone have tips on how to do that successfully?
I'm curious to know if others are doing anything else to get an even better experience, and I'm also curious to know if these settings work well for others who are struggling with the lag issue.

To make the density in /data work, you need to use this command in local.prop:
qemu.sf.lcd_density=260
And the permissions on the local.prop file need to be set right. Make them the same as the build.prop file.

I have the same settings.
The one that made the major change is the Lagfix which transformed the general snappiness.
Though now i am worried by the warnings about potential bricking so am not doing it daily.
perhaps once a week.
Not at all sure if the other changes did anything.
Also what would be the advantage of changing lcd density (which I havent done)?
thank you for the suggestions in this thread. my Nook had become so slow as to be barely usable. I'll give these ideas a shot.
Tried Lagfix. Got my 1stCM stuck at bootanim. Scary. Luckily a 2nd boot worked...

My X has been running slow and a little funny. I have froyo 2.3.15, with FlyX Rom, Revolution Themes, LauncherPro Plus, and Beautiful Widgets all running. Revolution was the last thing I added about a week ago and ever since then, it seems to be running different. Its slower to react, doesn't change from portrait to landscape very fast, whenever I unlock the screen, if I'm holding it straight up and down, it always opens into landscape mode. This seems like a pretty standard setup to a lot of people on here. Any advice and info on this topic would be appreciated, or just conversation about what others are running similar or different. Thanks a lot!
(also, I ran quadrant benchmark with scores between 1440 and 1495)

I cannot recall whether or not FlyX includes the build.prop modifications or not, if not you would definitely want to make those. Other than that the only other thing I would recommend is giving MinFreeManager a shot, it changes the "low memory" requirements for the built in memory manager (task manager) of android. If configured properly it can really make a difference in both battery life and performance (not speed, but responsiveness). It does not do it for you, it lets you set the fields, so learn how to do it first, it varies depending on your use of your phone, I don't run any facebook or other streaming applications so my settings are 6,8,16,60,60,150 but this could vary greatly, and may adversely affect others, so read up on the app in the market.
Again that app will improve responsiveness, in that it will give you less delay when swyping the screen in the UI and such, in that your phone does not have to kill a task to free up memory to complete the next task, it will not improve benchmarks, at the same time, poor memory management will give you poor performance in real world use but may not affect your benchmarks, another reason that benchmarks are poor ways of measuring performance.
Outside of that, what it really comes down to is our Android systems need hardware acceleration... Google really needs to get of there... well... you know... and get with the game here, based off the recent discussion and their advisement to manufacturers to hold of the release of tablets until the next android release, I am hoping they are currently implementing it, but without GPU hardware acceleration in the UI and web browser, we will constantly have the appearance of choppiness and the illusion of poor performance even on our overqualified phones... it is one area where I am sad to say the iPhone has us beat... very sad to say... as a matter of fact, I just washed my mouth out with a bit of soap...
EDIT: a good example of how well that application worked for me over actual "tasks killers" on the market such as task killer and such... before having this app installed and configured, a quick investigation of "settings, applications, running services" and viewing the available memory, it would display "Avail:16MB+98MB in ##" after having this app and having it configured it displays "Avail:72MB+116MB in 26" I am assuming my poor UI responsiveness was due to the first of the two numbers...
Yeah I always hate to say that about iPhones too but they do seem to keep the same speed and responsiveness ALL the time... Oh well, they've been around a little longer so Android will just have to keep working on it. I believe it'll be there soon. I will try that app you recommended. I appreciate the speedy response.

no problem, yeah, the iPhone has had GPU hardware acceleration in the UI since it came out, they structured their OS around it, Google chose otherwise, and I can only hope they regret that decision now... but hopefully they will make amends for that...
just make sure you read the post referenced in the app itself. It is written for the HTC Hero which only has 288MB of Ram as opposed to our 512MB Ram, but it still basically applies.
Keep in mind:
It does not automatically set on reboot until you tell it to, do not tell it to until you are sure the settings you have set do not mess with anything.
You probably will not notice a difference for about an hour... at least that's how long it took for me to truly notice a difference... I'm not really sure why, it apparently took that long for the priorities to take affect, and get the right processes killed, etc., etc. After that, especially later that day I was truly noticing a difference, especially in typing... I have always had a delay when typing on this phone, and that seems to be gone now...
yeah i was guessing that. i read an article at androidcentral.com about it and just set it to aggressive for now. applied it, but the specs under "running services" haven't changed so i'll give it an hour or so. i'll let you know how it turns out. thanks again!

Sounds good, your welcome and good luck!
If those settings work out for you without any problems, you'll probably want to up them a bit, it might say aggressive, but they are only so aggressive... If it makes a big difference for you then stick with them, if you still have slow down, and you are running what you described before, you can probably get away running settings similar to what I posted, just don't have them set on boot just in case, if they don't work out you can always set them lower or back to a preset. It is definitely something you can expiriment with, if worst comes to worst, you can always reboot, but as long as you don't touch the first 4 values, you won't mess anything up, the worst that you will do with the last 2 is temporarly screw up facebook sync. or something similar, and really you can get away with changing the 4th value to, it just has a chance of affecting more things, but I doubt you'll end up affecting anything with values around 50 anyway. Like I said, experimenting never hurts, slow phones do... Just keep an eye on it ;-) good luck again.
To add a little correction.if you are running fly x then you are not running 2.3.15 you are running the earlier related release it Is based on. Even if you did have2.3.15 before installing it fly x over writes the system to the files it uses. All roms do. Do you actually have like 2.3.9 I think

It does say 2.3.9. I inquired about this before because I used teamblackhat to get .15 and the system never seemed to change to .15 every time I tried to download it... I guess that's why, because of flyx...

Hey don't thank me, thank the creator of MFM, I'm pretty sure he was one of the first to discover the power of Androids integrated minimum memory management, if not the first. Just glad to share my discovery of his discovery haha. But yea, to be honest I don't even use a custom Rom anymore, it runs so quick just having that (thought it works even better in conjunction with your standard simplistic task killer such as "advanced task killer" just to kill apps in the foreground after you are done with them, since many apps don't include a way of closing themselves out...
I still try the custom Roms out and play around with them for the hell of it, but as for right now, I rely heavily on corporate integration, and most of the good blurless Roms remove features required for true and proper corporate sync, such as calender sync and the like... and I just don't like touchdown pro... So this helps me out greatly... remove some bloat, throw launcher pro on there, and get this fix fired up, phone runs like a dream... now if only they could get exchange active sync running like it was on Sense... best implementation I have seen of Exchange active sync so far... I do miss that...
Well after all the advice I ended up installing the zapx rom last night. Wow! It is sooo fast... everything just responds and reacts so much faster than before. I suggest installing zapx to anyone. Best rom so far I think...

Dear deio,
I have a perfect perception of smoothness and I'm not going to lie to you - I have A500 with Lightspeed 1.0.4 with stock kernel. Runs SMOOTH AS BUTTER! My brother owns an iPAD 2 and trust me I've played a lot with this useless (for me) thing if that's the idea of "ultimate smoothness". OK, this thread is not about iPADs vs Android tablets (no matter your conclusion that every Android tablet is ****ty), its about the lag OP experienced with OTA 3.2 . huurux , either go ahead for a custom ROM or return your device for replacement.
Having the same problem since i downloaded ota 3.2. When i say lag, i meant like it takes me a couple of minutes to open up an app (not a specific app, almost any app causes the lag) and even that, when i try to execute anything with the app it takes a few more minutes. Android Market also tells me i have updates for my apps, click on update, and the download status bar will marquee endlessly and would not let me download anything. Was thinking i had a bad update.
My question is (and help me out cause i am a noob): Is there a way i can reflash the stock ota 3.2? I have tried the "check for update" but it will just tell me that my android is up-to-date. Please help, have tried looking in the forum but couldnt find a similar solution.
Another noobish question: If i factory reset i assume it will wipe all data. Is there an easy way i can reinstall all the apps i previously had before the factory reset? If so, will i be able to retain all the progress i made in the app? (eg: game progress, rss list, etc)Tks in advance =)

Get Titanium backup from Market - its the most usefull app for me that's why I got the paid version. It will backup all your apps with data. The free version would also do the job for you but the batch process of restoring apps later will require pressing OK on each app that is currently being restored.
Thanks for the fast reply. It seems that i am not able to download any apps from the moment because of the problem. Although internet seems to be working.
Try to download Titanium Backup from their web site. As for the lag, I'm on stock 3.2 and I don't have any lag, the tablet runs even faster than with 3.2, so something is causing the lag on your tablet, I suspect a bad application, it happened to me with my iPad and iTouch, that went slow as molasses, and it was bad application. Uninstalled and everything got fine.
So for those so quickly to blame any android tablet, pleas check first that really you didn't install any crap application, specially cracked or pirated ones, that is slowing the system.

I also have this "LightSpeed" ROM, is laggy as hell, this is not a hardware problem, tried with a different Iconia, I also had a TF101, it was a bit better, but lack of USB on the slate made me chose the Iconia.
Sorry but this is about all Android tablets, and I must apologize to you, but I don't believe you. There is no smoothness in ANY Android device.
Ok, recommend a ROM that has the lowest lag, I'll try it.
I really don't get any slowdowns. I am however using tabooney with Richard trip kernel set tobuserspace in setcpu. Its been really good for me

I'm running EZTerry's "stock" rooted 3.2 OTA ROM without any lag, choppiness, or basically any issues at all. My battery life is what it's always been since buying it in May.
Unfortunately for the OP, if you accepted the OTA you can no longer root so apps like Titanium Backup or flashing a different ROM are no longer an option. You'll have to wait for someone to get root for OTA 3.2.
If you don't mind losing some of your apps, you can try a factory reset, load one app at a time from the market, and see if you can determine if an app is causing your problems.
Deio, continuing to call the A500 community liars and idiots in thread after thread is likely not going to result in much help coming your way. At this point my only advice to you is to eBay your A500 and go buy an iPad. Clearly, the A500 is simply not the device for you and you're never going to be happy with it.
deio, buy a f***ing iPad and leave us alone!
Lag
I've noticed a significant lag when the power plug is on (especially the touchscreen), as soon as I unplug the power cordless everything run smooth... weird
android 3.1
My roommate has the Transformer and I have the Iconia, we both lag like hell every two to three hours for about 5-10mins.

I also have the power/charge lag problem. I'm on stock rooted 3.1 using Richard Tripp's kernel to OC 1.4. Lagging during charging/ac power has been a problem for my A500 since new, with no root. Something about this engineering that makes it a problem for some units.
Going to load Taboonay and see if it makes a difference.

My config A500 3.1 rooted, I didn't have this issue be4 3.1 update.
Try thors newest v11. I only get lag on this website for some reason, it takes a quick second for the whole page to show. Its hit and miss. Every now and then it will go away. I watch alot of 720p videos. Both streaming from my home server or downloaded to one of my sdcards. All my daily uses, email, surfing, videos, etc. have almost no lag.
Ok here we go...
The best I can guess from reading about all of your lag problems is that there is a program or programs that are running in your background processes and eating up cpu/memory. Go to settings-applications-running applications and see what is on right now; subsequently see what is running directly after a reboot. If a bunch of random apps are running, it is very likely they are causing the lag. Especially if they are syncing or accessing the web. My suggestion would be to either uninstall these apps or go into their individual settings and turn off anything that would have it constantly working (not just running, it is ok for some apps to run in the background, as Android is programmed to control memory usage while allowing apps to run when not it use, but specifically 'working' in the background will eat up resources). Also, how often do you have your syncs scheduled? Any info that you do not need to have constantly synced (ie backup email addresses, facebook, weather intervals, etc.) should be either turned off or set to sync only a few times a day. For example, I have 11 running apps right now (been running without a reboot for a few days), consisting mainly of core Android processes, my keyboard, email, cpu scaler, and just 2 apps that I have downloaded that run in the background (mind you I have about 50 apps installed).
Furthermore...
All this talk about the iPad and how smooth it is...that's because it utilizes hardware accelerated graphics, something that Android will now have with the release of Ice Cream Sandwich 4.0. True, the level of smoothness on an iPad typically surpasses that of an Android device, but that is soon to change. Then what will the iPad really have? A boring home screen that consists of nothing more than only our app drawer and a ton of games. Android brings WAY more to the table, no question about it.
Going on...
I am running a custom rom (Taboonay 2.1b) with an overclocked/undervolted processor (1.4ghz -150mv) and my Iconia gets kick ass battery life. I need to really try to kill this thing, no joke. I play hi-def/3d games, watch flash content on the web, Netflix, internet browsing, email, create word docs, use external usb peripherals, and more. To get the best battery life you just have to be smart about it.
Suggestions:
Turn off auto backlight. I don't think it works very well on the Iconia anyway, I have my brightness set at about 20% and it's perfectly visible (if you're used to having it brighter give it some time, you'll adjust) and when I am in bright light I simply change it as needed.
Check sync schedule. Weather really only needs to be updated like every 3 hours at most. Do you really need to know the temperature AS it changes? Don't think so.
Do you have multiple email addresses? Unless they are work related, you can probably just set them to sync manually and check it a couple times a day without it turning on itself.
Facebook/Twitter syncing is the devil. Unless you are a 15 year old girl that needs to know what her bff is doing at all times, slow down the sync on these apps!
Is your WiFi set to turn off with your screen? This is a BIG ONE! Settings-Wireless/Networks-WiFi Settings-WiFi Disconnect Policy-When Screen Turns Off. You'll notice a change immediately.
For some more info on what's killing your battery, and therefore more than likely sucking up resources and causing lag, go to Settings-Applications-Battery Use. The blue lines should line up accordingly: Your device should only be Awake and have the WiFi on when the Screen is on, except for a few dashes here and there for normal syncing. Large blue squares of Awake when the screen isn't on means something is running in the background that probably shouldn't be. WiFi on all the time kills battery. Get it? Also, the list of apps that take up battery should only be ones that YOU KNOW you are using on a constant basis. If something is on there that you don't normally use a lot, it means it's running in the background and sucking up a lot of resources (other than screen, tablet idle, and Android OS, these should be there).
Moral of the story...
I gave my 3 year old kids my iPhone. It's a kids toy, same with the iPad. Period. An Android device is one of the most powerful, customizable and capable devices available. There is a lot more that can be done with it than with most other more simple devices. With great power comes great responsibility. Take control of your device, what you do with it and what it does. Lag? What lag.
Phew. I'm a little drunk at the moment, so hope I didn't go too crazy here. What was this post about by the way? Ha! Hit the thanks button if this made any sense to anyone out there
Honestly, I couldn't have said it better myself. I'm running stock unrooted 3.2(mostly because I've been too lazy to revert back to a rooted ROM)and have very little to no lag. Realizing that its all personal perception and that I gave my Ipod to my kid so I don't really have anything to compare it to, I'm way more than happy with the performance of my tablet. The only time I have to wait is when I open up the Acer content folders, sometimes it takes a second or two for them to open. I can definitely live with that, if the trade off is a fully usable tablet that I can customize to my own needs. Battery life is well above expectations as well for me. Usually two days of semi-heavy use before I start to get that panicky feeling that comes when my battery meter drops below 30%.
Ok so for those that have been able to upgrade to ICS (P6800 owners) what are your toughts?
Now this is what i am looking for:
A) What you like
B) Don't like
C) What would you like to have seen included but wasn't (if anything)
And since having the update what are you looking forward to doing that you couldn't or wouldn't with HC.
Please don't post any issues you have after updating, that is not what this post is intended for.

Well i don't think that i don't like anything but i haven't really found something that is faulty. It is definitely faster as i immediately noticed that it took less ram, than honey comb, to run. Feels pretty fast with go launcher HD to me and i love it completely. Although i thought that there would be camera improvements as tab 2 7.0 has the same 3 mega pixel camera but does 1080p recording. So i thought that it might be done with tab 7.7 as well with an ics upgrade.

Well I love it to and made it up with Samsung:
- first with ICS that tablet really rocks it already did but now it's almost perfect
- smoother faster it seems especially the OOM killer seems more smart, and less memory used it seems
- no more problem with Itap rdp right click with bt mouse
- something I never mentioned. : I developed or try to develop a clone of pronto remote and debug using adb wireless
With HC I could not connect via adb on the computer using ethernet to adb wireless wifi due to packet loss... So had to disable ethernet and enable wifi. With ics no longer this issue...
- I used to have frequent sleep of death for the moment none
- I listen radio everyday through tunein somehow at around 1pm HC always rebooted by itself. Never bothered to figure out why... Now this no longer happen...
- no wifi issue ( some ICS user reported problems). I never had neither with HC except sleep of death or reboot that might be related to wifi?. I use Friztbox 7340 AP.
- my 100+ aps. Seems to all works (of course did not test deeply since yesterday) except gmd gesture control to hide the control bar
-once in a while but quite frequently using HC my EXCHANGE account would vanish...had to re-create every time... waiting to see on this one...Could be my remote application leaking....
So all in all very very happy with this tab and Samsung... Patience was what I missed
- I did wipe and did not have any problem if we refer to brick bug... But you never know...
What I like less
- dialog box theme gray without frame around
- it seems Samy addressed bur-in doing the bar black now....
I preferred it before and I don't have noticeable burn-in ( since march and extensive uses) except using color filter and brightness turned all down then I see slight yellow discoloration... Nothing to complain for me as the TAB HW screen etc are just so great IMO and outweight for me this small detail.
Seriously the TAB rocks for me...
Can you imagine 7.7 with quad core and dream about a 1080p SAMOLED display in a 7'7 TAB for me the perfect size!
I guess I continue buying Samsung.... Despite some of my previous comments... Waiting for the ICS on 8.9 now for my girl friend

My first impression
i installed the firmware through odin. it was not available on kies. so if i have to claim warranty ( god forbid ) then i guess i have to flash my country's HC firmware back
what i liked is that it is noticibly faster than HC. Apps load faster. lag is less. starting button lag is less. there have been no FC's and almost all of my games are compatible.
what i dislike or rather disappointed is that it does not look or feel much different than HC. no added functionality except Face unlock. what i would have liked is some features of S3.
i am running this for almost 24 hrs now. battery usage is same as HC.
I like that this device is actually usable now. I think I'm going to use it as my main tablet now. I didn't use it with HC because it was just so slow compared to my gt8.9 (running ICS rom).
My first impression: TouchWiz seems much smoother, Go Launcher HD feels the same. Under heavy usage of widgets TouchWiz is still great but Go Launcher HD not. I do love some Go Launcher features so I played around a lot and also tested the new 1.11 beta. But is still less responsive.
It's like a faulty motherboard replaced by a newer and faster one.
Seriously, like a new device, snappy, responsive, seems less battery hungry.
There is one 'custom rom" available, where EDaN has deodexed and removed some bloatware. I took that rom and took out everything social,photo and video editor, and some other minor crap.
Having 60 apps installed and tested it's like Christmas.
- dislike
had to discover I must install busybox to get Titanium working
had to install supersu myself, no biggy
no software based CWM, havent found compatible one, but one thats reboots to recovery anyway.
No powermenu at powerbutton
ugly blueish tint around quickmenu (with shortcuts for bt.wifi etc)
This all will be fixed when chefs get source or get impatient and offer CWM zips

my only gripe so far is that if you increase the font size to Large, some apps (mostly system apps) seem to have the font go to 'super large' e.g. google play, settings menu, whilst some apps its perfect.
Conversely, going down to medium, most apps are back to Honeycomb tiny font problem, whilst the system apps are fine
Seems like Sammy tweaked the touchwiz stock UI to display fine on medium size, without thinking that 'hey most apps the user will be using needs it set to large hmmmm'. Hoping AOSP ROMs will get around this issue
The tab is more responsive overall. Feels like a new device. But still not loving touchwiz--wish this is a pure Google device. Installing Nova Launcher partially fixes that. Only app not working out well so far is Battery Monitor Widget Pro--the mA usage keeps showing "0". Just about everything else survived the upgrade with no issues.
Add: mA information in Battery monitor widget works is set to "estimation" rather than automatic. So that problem is solved...
I never used tw always adw launcher ex on this device, everything is smoother with ics now we just need some custom roms and kernels so it can catch up to my galaxy note and asus prime

It only seems to work with the Samsung keyboard. I thought that was also the case in 3.2?
I'm truly loving this tab with ICS. One huge problem is with my WiFi. I experienced once again as it just disconnected and never connected again until I shut it down completely and turned it back on. Logged onto another AP. I hate this problem as I thought I had fixed it. It seems like the WiFi module is overheated and shutdown or something....*SIGH*
when browsing, going back to the previous tabs is still being reloaded. That is my only gripe so far.
Other than that, everything is smoothhhhhh...

Impressions.
It's good stuff!
First: Hotmail seems to be staying put. Had big bothers with this as account would dissapear from tab. Seems to be fixed now, but need more time.
Second: SD Card behaving. Sweet.
Third: No waiting around for unlock screen to pop up when power button pressed. WTF was that anyway?
Fourth: Swype behaving itself. Kept on getting beeps before, and i would have to change to Samkey and back to swype. One crash so far in google translate.
Fifth: Browser no longer reloading all the time to homepage. seems more stable.
Sixth: Youtube actually responds when choosing a vid. If you hit back before and chose another, it was no longer responsive.
Seventh: AR much more responsive. 1sec response time. instead of 3-4. Overall response time much boosted. Has crossed the line from WTF? to hey... Sweet!
0'ed: Sammy did our super bloody expensive tab first. THANK YOU!
PS: flashed XL4 (United Arab Emirates) with Austrian version.(ODIN 1.85) Not a problem. Did Full Reset before flashing though. All went smooth. Im a very happy camper! Hope i could help.
Updated to the official OTA JB update a few weeks ago, and at first thing seemed great. The UI looked smooth and things seemed to have an increased efficiency. However ive noticed over the last week that things have been going wrong.
Delays opening and exiting apps, dialler being even slower than normal ( i know this has been an issue for others).
Looking at the device's ram usage its been at the 800mb mark, which i thought was quite high.
Anyone else been having similar probs?

The stock recovery only has a factory reset option (deletes your data and apps).
Alright, did you install any new apps before the problem happened? Any dodgy widgets? What's the service using the most amount of RAM? (Settings -> Application Manager -> Running -> Most app using ram, look at the one with the highest MB's).

One its a question .
Two i would backup data and factory reset first .
jje
largest running apps being:
Settings 67mb
Google services 22mb
Samsung Keyboard 21mb
Viber 13mb
Facebook 17mb
The rest are under 10mb
Same happened to me, I factory reset the phone and it runs too good to be true. Also disabled some bloat in app settings,not sure how much difference its specifically made but the phone flies.
Additionally there are 4 settings that will speed up your phone, allow dev options to be on, find force GPU rendering and turn it on. Then above that there should be 3 settings that each allow numerical settings, set each of the 3 to 0.5 to reduce the time that your phone loads up advanced displays animations.
You're welcome.
Sent via second class post, so I don't expect you to read this for at least a few weeks.
From what I remember force gpu rendering causes apps to use a lot more ram. Could be wrong but it will probably be an issue for those who complain about low ram.
I know it might seem a bit obvious but have you switched Power Saving Mode on?
Because for half a day I was convinced something was seriously wrong and thinking the worst until that face palm moment when I saw the icon lit up.
I definitely notice an increase in performance with it on but haven't noticed any adverse affects like more ram consumption, in fact the only problem ever was that the app androidify didn't work

Does this actually reduce the loading time? As far as I understand this setting just plays the animation at double speed, so it makes your UI appear snappier.
Minimally I assume because it's not processing the animation so much. In all honesty I can't give a definitive answer though.
I think forcing GPU does though because your processor is free top load up all the back ground processes while your GPU loads the visual aspects, efficiency is always the best way and most things on jelly bean should be optimised for it.

So I just bought a nexus 10 and among the many reasons for getting one, I want to take notes with it. I've bought myself a nice stylus that works wonderfully on iPads and my galaxy nexus phone. However, writing with the same stylus and exact same apps on my nexus 10 isn't working as one would hope. It seems to lag quite badly in picking up where my stylus is and this forces me to write very slowly so that it will pick up all of my strokes, thus making it pretty much useless in a classroom setting, but, like I said before, I don't see this at all with my galaxy nexus.
So, why am I seeing such a huge difference in performance between these two devices when (I assume) the nexus 10 would be so much more powerful than my phone? Is it the apps or the hardware? And how do I fix this issue without just writing my own note taking app?
I faced no problems working on freenote/ handwriting or myscript calculator ?? I might loook at the stylus and not the N10

But I've seen this issue regardless of the stylus used... Even with my finger I see a lag.
I also tried free note on my phone and tablet and am seeing a lag only on the nexus 10. I seriously doubt that it's the stylus, it seems to be isolated to my device...though, I haven't tried this with any other nexus 10 device. I don't know anyone else who has one.

Are you on stock? Or did you root and install a custom ROM? what about a custom kernel?

Also, I tried using Seeder but saw no significant difference on my device.

I'm still having this problem on stock 4.2.2 (as well as the latest CM nightly), and was wondering if anyone had any fixes. My Jot Classic works okay, but not well enough for any serious note-taking, and considerably slower than the same app/stylus on my nexus 4 and 7. My main issue is that it isn't sensitive enough to write small exponents and subscripts.

Today, I finally got my Nexus 10 and I started to investigate this ominous delay or lag. I indeed observe this lag on my Nexus 10 in LectureNotes and all other handwriting apps that I tested. As far as LectureNotes is concerned, I did a number of careful timing measurements and I think I can definitely exclude that the delay is due to slow drawing or anything like that. It seems that, on a Nexus 10, Android sends input events with a noticeable delay of around 250ms or so if they origin from touching the display, this is why a drawn line lags behind your stylus or finger. However, the delay is absent if you use a mouse (connected via Bluetooth), and hence there is no lag and the line follows the mouse pointer very closely. This is somewhat bad news, as this means that this problem cannot be solved within LectureNotes.

If that is the case, could the input delay be tweaked or removed through kernel modifications?
@EniGmA1987: If my explanation is correct and if one can modify the input handling, this might be possible. It seems that users with non-stock ROMS do not suffer from this problem, but this is just my impression based on contacts with LectureNotes' users and might be wrong.

I feel that have solved this issue for my current configuration. I've found that with the following setup, any lag that may be occurring is so slight that I either don't notice or I don't mind it:
-Get a stylus that actually works well (I had accidentally bought the first generation of the Adonit Jot Pro which has horrible sensitivity. However, after obtaining the 2nd generation, I've had no problems at all... one of my biggest reasons behind the lag was this 1st generation stylus)
-Stock 4.2.2
-Run Seeder 2.0
-DON'T force GPU handling
-Using LectureNotes Pro
-Create all lecture notes notebooks with a much higher resolution than what is initially set as the default. (This is what made the biggest difference)
From what I've observed, it seems to me that the best explanation behind any significant lag on this device is its extremely high resolution. I assume that most handwriting apps are programmed in such a way that the increase in pixel count hinders the sensitivity of the app itself.
