I just did the lag fix mentioned here: http://www.xda-developers.com/android/one-click-lag-fix-for-galaxy-s-i9000/
on my captivate and got a score of 2185... It's my 1st time benchmarking the phone. Is that a good score?
yeah but did your actual perfomance change?
I got 2190 on a reboot after I manually did the fix. Still have all the AT&T stuff, root and side loaded but other than that stock.
The phone does feel a little faster, its not twice as fast as it was but scrolling around and launching programs does seem faster. Placebo effect? Maybe.
Nice
I tried it as well and I can say I have definitely noticed the speed bump. Well worth the three minutes it took me to read and install.
It doesn't really feel that much quicker, more like smoother since the lag is pretty much gone.

yeah it changes all right. things load much faster. webpages, apps etc... you will be amazed
I ran the fix too. The phone finally feels high end. Every app is now responsive. Xda app flies now. The market loads the"downloads" tab in 1 second instead of 7 dolphin is as fast as the stock browser. It's really great.
That said, the quadrant score is bogus. The lag fix sets up a loopback for io writes so quadrant produces a completely bogus and inflated ui score.
I have an overclocked Samsung Epic and it the improvement in speed in everyday use is significant. Because the processor voltage is set lower than stock there is no sacrifice in battery life. With the Asus Transformer do you get a definite and significant benefit from overclocking? I am not talking about test bench scores but real world noticeable responsiveness. When I skim through the forums it is difficult for me to tell? Some people swear by sticking with stock. I would appreciate others perspectives.
Thanks
The improvements from overclocking vary on the application.
Home screen switching is choppy regardless of overclocking simply because the launcher lacks optimization. Browser performance is improved a little bit, but mainly remains unchanged as well. Games run noticeably smoother, especially Fpse. Task switching gets a small boost, as some applications will be able to load faster.
If you're a big gamer, overclocking is definitely worth it. For everything else, it won't make much of a difference.
I haven't played too many games (mostly Stardunk and Stupid Zombies) on my TF, but I haven't noticed any issues with them. I have also played high profile 720p video with absolutely no stuttering or artefacts.
In other words, I haven't felt the need to overclock yet. But if you are doing heavy gaming and/or video processing of some kind, it might be worthwhile.
For me, there's hardly any need to OC. It all depends on what you wanna do. To many people who play a lot of games on their TF, they report increases in performance (especially with emulators) but on other things I never really noticed any difference. I'm currently underclocking my TF, and have been for about a week, with no noticable stutters or performance issues and have great battery life.
And it's not really an "effort" to flash a new kernel... the hardest thing is waiting for your device to boot up again...
I have a transformer, galaxy tab 10.1, and a xoom. I've used just about every kernel that can be overclocked for each one of them, and to be honest I haven't really seen any improvements from them. I don't really play many games on my tablets though, so maybe there really is some benefit in that area.
Galaxy's screen
How do you rate the screen of the Galaxy Tab 10.1? Is it as good as the Super AmoLED (+)'s from Samsung mobiles?

This seems so counter-intuitive to me. If you overclock a PC CPU there is a very direct correlation with performance. There are always limiting factors such HD acess, etc., but there is a definite and noticeable difference across applications. What is even more surprising is that we are talking about very large % increases vs what people can do in the PC world. People are overclocking these CPUs by 50% plus...You would think you would see a very noticeable improvement but that doesn't seem to be the case.
My main interest is in browser performance. For example, XDA forum pages load extremely slow in all browsers I have tried (stock, Opera, Dolfin) with 5-6s to refresh vs instant on desktop browser. Also flash video tends to freeze and stutter some times. My internet connection is over 20Mb/s down and 5Mb/s up. I was hoping that I would find overclocking safe and provide a noticeable improvement.

So for web page loading you haven't noticed much of a difference? How about flash video?
Thanks.
Overclocking can be a bit like collecting .. 'string' , because it is mostly done for the sake of itself, kind of like the many Ham Radio fans who talk about their "rigs", etc etc.
Yeah, of course if you can get, like in the old old days, a celeron 300 that overclocks to 450, and is dead stable, it was noticeable, and if you had a droid 1, which overclocked (many did) with ease from 500 to 1000+ , then it was again, noticeable, just not a staggeringly 2 times increase, because there are too many other factors.
The number of bus errors, and retries and slowness of the original bus speeds, and other components makes for a not-quite-as-expected by the numbers 'increase'. I would still mess with it, but not for the obvious reasons. I like under-volting more, and over-clocking only the slightest bit where nothing ever crashes or FCs. The moment you overclock, you really shouldn't be asking questions about 'Why does blah blah netflix crash?' because it crashes because you overclocked, and nothing else matters until you stick a kernel back at stock in there.
The other thing I love about alternate kernels is that you've got control of what modules you either compile in or compile and load as .ko files. cifs, tun, ntfs, whatever, it is all very useful, so there are lots of good and not-as-good things about it.
One thing I hate is when a dev insists on creating a kernel that has a 'default' speed greater than stock so that you've instantly got an ordeal if you've got one of the many gizmos that will not overclock to his default (like 1.6 to pick a number out of a hat).. Just make them all start at default, then allow us , the users, to setup overclocking via testing with setcpu or some such thing. Much easier than basically bricking things right off.
I sometimes look at those guys that overclock 'seriously' (by 3-4 times) using a container of liquid nitrogen that lasts for ~5 minutes and it is all for bragging rights, setting records , etc and think they're insane, but that is also part of it. Some are happy if they can just post here that they got 9,000 mF on some test despite not being able to do anything else reliably.

Great post!
+1
Very philosophical ! ;-)
I guess what I am getting at is if you overclock to 1.2Ghz-1.3Ghz on the Transformer can you have a stable system that shows an appreciable improvement in responsiveness? Moving from hypothetical to actual...have you done this? Any specific kernel?
The engineer in me is looking for a definitive answer. ;-)
Thanks.

Yeah, I've done this, just not on the TF yet. I'm working on a kernel right now that doesn't have OC built-in and activated at boot, so that we can use setcpu to screw around with it and find that 'sweet spot' that works for us, also under-over-volting. What I'd really like is to build in all the modules I like, setup over/under-clocking-volting and have it boot at 1 G. I mean, a dual-core 1G is nothing to sneeze at, and then try to ramp it up without screwing with over-volting immediately. I never like other peoples ROMs or Kernels because they have made their own crazy judgement calls. I like my own crazy judgement calls
Here's what I've noticed: When you have 'up-to-date' technology , as we do, in the TF, then overclocking that is totally stable makes a difference and it is noticeable. For me it's the FC's that kill the deal, but this chip and box appear to have plenty of headroom so I'm guessing that 1.2, 1.3, 1.4 are all good possibilities.
Example: My HTC Incredible phone has been overclocked to 1.1 from 1.0G for ~a year or so, and it doesn't FC, and it is faster, noticeably than at 1. It's only a 10% increase and yet it feels much quicker, so go figure. Those things are also subjective, so grain of salt... Example2: A stock droid1 is one I took to a double overclock, 550 to 1000, and yes it was faster at some things, but the underlying infrastructure didn't really support the faster CPU so I really never noticed a 100% increase that matched the clock speed. I left it that way for a year without any damages and it still boots up fine at 1 G.
In another post I started, I was asking what keys were required to boot 'safe mode' which exists in android OSs, and if I knew that, I'd try one of the OC'd kernels right now. IF not, I don't feel like unbricking again.
If you're interested, here's a good link for building your own: (generic android, not TF really:
http://www.droidforums.net/forum/rescue-squad-guides/31452-how-compile-your-own-kernel.html
Thanks for the response. With such a large community of Transformer users I am hoping to find a solid, conservative kernel that I can overclock with. Creating one myself is beyond my current technical capabilities.
Maybe i am wrong but it looks like there is something weird with 2d/interface performance of my Sensation.
Currently i am running latest Hypersensation with latest Faux's kernel (ADW Launcher) and i have tested a lot of other ROMs and launchers..but on all of them i am getting nonsmooth interface. Kinda laggy.
I mean, in sense, everything is fine (in the meaning of that word, not supersmooth but fine), but when i try Zeam launcher's drawer (with 6x6 grid) which is superlightweight it gets laggy. In ADW (6x4) it's laggy too. In Go Launcher not too much but i am still not happy. And it's the same with Launcher Pro.
And effected homescreen - switching is not smooth at all. I even tried overclocking my cpu, but it didn't help.
Before some time, by sensation has fallen on the floor by left down corner (and now i have deep scratch on the external casing) - could it damage by cpu in any way? I hope not
I am getting scroll lags in some apps (twicca), new twitter app (released today) is laggy as hell (when pulling to refresh, to be accurate) and new facebook.
However in games it's fine and i am getting around 12000 native cf-bench score with overclocked (1,5 Ghz) CPU, so this is indicating that there is no damage to CPU.
Maybe i am too demanding, but this performance in ui (which you are using most of the time on phone) is not what i expect from 1,2 Ghz DC phone.
Is anybody out there experiencing similar issues? Anyway to fix them? Thanks in advance, guys!
I have attached twitter video...30 fps via screen recorder high quality settings:
http://www.youtube.com/watch?v=r_mnEz9tl3E
I suggest using a Sense rom, they tend to have better performance, but switching launchers. The guy who makes HyperSensation also has a no sense rom, try it out, it's really fast and smooth. As for ADW, get ADW Launcher EX, ADW just plain sucks, but EX is very fast.

As long as it's still running, I doubt it. These phones dont have any moving parts, so it's not like you busted a cooling fan or anything. You're not the first to bring performance concerns to the Sensation. And frankly, I've noticed it too sometimes. At times I feel like I'm using my G2, but the good news, ICS will have a GPU accelerated UI (like the iPhone does) so performance should greatly improve soon, hang in there brother.
Thanks, i forgot to mention that i have used all launchers mentioned above with sense rom, with sense disabled via app manager (frozen) and e. g. mentioned zeam sucked. But iwill give ADW EX a try..especially when it costs 0,1 euro
http://forum.xda-developers.com/showthread.php?t=1350492
There's that non-sense rom I recommended. ADW EX is definitely worth the money, you'll notice an instant performance difference over the standard ADW. The only thing thats laggy about it (on any phone) is if you set a transparent drawer, since it's not GPU accelerated, that'll half your FPS. Hope it goes well for you, it's a shame that even with Sense disabled, you're seeing problems.
Edit: Have you tried either the Faux or Bricked kernels?
Thanks for tip with ADW Ex, it is totally smooth now Zooming animation still isn't perfect (when going from homescreen to appdrawer) but its ok. I have never thought that EX is this big performance improvement.
Funny thing is, I have the same issue. I changed the zoom duration to somehting like 300 or 350, speeds it up so it doesn't look as bad, but I can't find a solution. Atleast EX is running good though.
Hello there! I was in the same boat with my sensation. Unhappy with the seemingly laggy interface of my new 2core phone. So I rooted to reverted aosp with 1.7 kernel and this is about as snappy as I wanted it to be from the start , I'd suggest trying it out
I have something to add. I tried multiple Sense and No-Sense roms, and that homescreen to appdrawer animation is perfect on all of them. I flashed the bricked kernel, but I'm pretty confident that that's no required to get that animation smoothed out.
Xda!
I have noticed in the last month my N5 starting to become laggy. To be fair I do push it to the limit. I have over 180 apps installed, it's rooted but on a stock ROM with some Xposed mods.
I'm quite aware that a factory reset would sort my issues out but I simply do not have the patience to input all my user data again to get back to where I am today.
Do the good people of XDA have suggestions on diagnosis for my lag, which has become noticeable. Is there a way for me to find out what processes or potential issues I may have which are begining to really hurt my performance and user experience.
Day one this was the zippiest device I'd ever been fortunate enough to lay my hands on. I want that back!
Do you ever wipe the cache/Dalvik? If not, I would start there.

Although I think there is a certain element of getting used to the speed of the device over time (so a perceived slow down takes place), the installation of apps that run on boot can also cause issues.
I think the best bet is Greenify anything that you don't need running in the background. For example, the BBC Weather app seems to want to stay in memory 24/7 when I maybe use it once a day. If there are 10 such apps using RAM, that will impact performance more than anything. The number of installed apps should actually have quite a small impact on performance if they are "dormant".

Thank you for the two suggestions.
Clearing the Dalvik and cache took an age but seems to have made an immediate impact once the system settled in on boot. I haven't updated my greenify list in ages so that is something I will box shortly....
