Quick question about kernels adversely affecting performance - Acer Iconia A500

This has happened to me maybe two or three times now, but I want to just focus on this time it's happening right now:
I installed the Villain kernel on 3.2.1 stock rooted rom, overclocked to 1.504GHz. Initially, the scrolling in landscape was as smooth as butter, but over the past few days it's become slightly choppy, and it's really bothering me, because I know I might have done something to mess this up. My question is, how do I fix this and make it so it has unbelieveably smooth scrolling again (just like when you pull it out of the box)? I think it's one of any number of things, really. It could be that I'm using cachemate, system panel pro, that I've used autostarts to stop a ton of applications from running at start up.
I just removed all of my game icons from the 2nd page (I only have two pages) and the scrolling didn't speed up, so it's not that.
Is there a a system app that relates to the scrolling that I might have disabled because it had a name that maybe I thought I could disable in autostarts?
Thanks for any help!

Stopping apps from autostart does not guarantee a performance improvement. This is not Windows and unused RAM is lost RAM. You're using more CPU power to kill constantly autostarting apps and services thus you're draining your battery faster. If a program resides in memory it still doesn't mean it does something. As an example, there were ROMs for HD2 that were developed to load completely in its RAM for superfast performance and yet battery life was still excellent. There might be apps that behave intrusive but that's not the majority of the cases. Try to isolate them with a tool like SystemPannel but first read its description @ the Market. Additionally try freezing with Titanium backup some of the apps you're definitely not using. Hope this helps.
p. s. Try switching from interactive to ondemand governor.

Ok, thanks very much for the info! I was talking to someone else about this earlier today and the made the same point as you.

CPU load too high - sluggish device

Hello,
i already posted this in some other thread. But here i go again maybe we get some more information from this thread.
When i made a cold reset, the CPU load of my Hero is about 10% (or lower) when measuring with "System Monitor" tool available from the market. Hero is scrolling quite smoothly as well.
After some time using the device i notice that scrolling through the Sense and the "All programs" list gets noticably slower and when i check back with system monitor i notice that CPU load is constantly high at around 30-40% and won't drop down again.
I already tried closing all programs including sense using TasKiller and Advance Task Manager, but neither one does the trick - the CPU load stays at this level until i make a hard reset of the device again.
Now it would be interessting to find out which application/process is causing this is it's also a heavy battery drain for the Hero.
this is actually encouraging news. this means the speed issues can most likley be fixed with new firmware release. or when donut gets put onto the hero. As I have heard that donut has lots of performance tweaks.
The biggest offender seems to be the HTC Widgets. I removed the people widget and the clock (after it the weather feed stopped working) after hearing suggestions and now my Hero is running blazingly fast. The only widgets I have now are the original android clock, the mini calendar and the large music widget.
People have been recommending NOT to use process managers such as taskiller to stop programs because not only can stopping the wrong apps cause problems (stop "clock" and your alarms won't go off, for example) but also it seems that Android is fairly intelligent with regards to process management and can handle it better by itself. You won't get much (if any) speed back by killing processes.
Yes that was also my suspicion - stopping apps might actually cause more (or even this one) problems than it solves.
But thanks for the hint with the clock, i already encountered this twice and came late to work
I removed any task killer software now, but even then i just noticed that i get the 30%+ constant CPU load phenomenon.
I suspect it has something to do with the market app or the installation of software as it seems it's happening right after that sometimes.

Performance drops after some time

Hi,
I have noticed that my Nexus' performance starts to drop after some hours on: going from one home screen to the other becomes quite choppy, and so do the animations of opening an application.
Have you guys noticed that too, or is it just me?
It was like this for me until I bought Advanced Task Manager. I have it auto end applications that I don't need to run all the time. It runs much better now.
The issue is RAM. The kernel that shipped with the Nexus One doesn't support the full 512MB of RAM. However, CyanogenMod 5.0-beta4 does and the difference in speed is amazing. With 26 apps running I have 167MB free atm.
But like stickerbob said, you should have Advanced Task Manager at the least.

Well, that doesn't really explain the performance drops. Does the phone run out of RAM, or not? It seems to be snappy again after a reboot, so there must be something.

That is what I have read, but it did not work for me. I downloaded the free version of advanced task man to troubleshoot the problem and found that most of my apps were still running in the background even when my ram was down to 10-20mb. That is about when the phone would start acting up on me. When I ended the tasks the phone would act normal again. So I just broke down and bought the app for $.99. If you do this make sure you exclude some system apps, if you don't your phone could freeze while it is trying to restart them.
10-20mb free is normal operation. This is how the OS is designed to operate, linux and even windows7 now also operate in this fashion (show very little 'free' memory). there is no performance problem with low free memory, purely a misconception on modern memory managment. Whats going on is that you have a buggy application, which is why 'killing' apps looks to be resolving your issue. You're only resolving the symptom, not the problem.
I never kill apps and have had weeks of uptime without any slow down. This gets rehashed over and over again by people claiming task killers help performance. The reality is they do nothing for performance, only nice to have around for that great once and a while an app runs away from you, or in troubleshooting if you have a poorly written app. It should not be anyones habit to do a kill all on a regular basis, if it were the OS would do this automatically.
btw, compcache has been known to cause this slowdown over time issue, it has since been removed from most of the popular custom baked rom's.

Well then there must be many buggy applications. I had to rely on Advanced Task Manager to keep my G1 running acceptably fast. The N1 slows down without its full RAM available so I needed to use Advanced Task Manager then too.
If the RAM is not the issue, why does having the extra 200 MB available make the phone run much smoother with 20+ apps running?

well technically no, it reallocates what is being used and frees up memory for programs currently running but non the less the OS manages itself
personally i close apps that i do not have going with the task manager. i seem to notice a performance difference if i do it manually, it takes 2-3 extra taps for peace of mind rather than relying on the OS to figure it out for me...

The speed benefits of CM's ROM isn't due to the HIGHMEM supporting kernel, but rather other tweeks he's done with his build. Extra ram is nice, but there is certainly no limitation with the 213 or so userspace memory that is available now. Android itself does not even use this memory, it has its own reserved memory space, userspace memory is only for applications to be loaded in. And there is speed for keeping as much of your applications loaded in memory as possible.
swetland said:
Roughly 220MB is available to userspace in the shipping build (ERD79).
Quite a lot of memory is dedicated to the radio firmware (41MB), dsp firmware (32MB), display surfaces (32MB), gpu (3MB), camera (8MB), a/v buffers (41MB), and dsp buffers. Much of this needs to be set aside for these specific tasks due to hardware requirements of very large physically contiguous buffers which can be difficult or impossible to obtain after boot once the physical memory space gets fragmented.
The big limitation though is that the Linux kernel needs to do a 1:1 physical:virtual map of general purpose memory used by the kernel and userspace (which excludes the special purpose stuff described above). This eats into the available kernel virtual address space, which is also needed for cross process shared memory used by the binder, etc. Run out of virtual memory and things get unhappy.
In 2.6.32, HIGHMEM support for ARM will allow us to avoid this requirement for a 1:1 mapping which will allow us to increase memory available to userspace without running the system out of virtual memory adddress space.

The speed difference I'm talking about is what I experienced when running CM beta3 and CM beta3 w/ highmem. The difference was huge. I assumed the change was mainly attributed to the double RAM available.
Even now with the full RAM available, things run faster when I end the other apps running. It's not necessary, but the difference is there.
It would be nice to be able to pinpoint which apps caused slow downs.
The best way I've seen this put I found in a thread where someone wanted to disable apps from auto-starting entirely. I saved it, because I though it was very elegant way to explain androids mem management.
equid0x said:
I just wanted to chime in here about the whole apps on startup thing....
Android has the concept of services which are programs that typically have a frontend piece, like a GUI for IM that you would normally use, that only runs when you are using it, and a background piece, the service, which is constantly running to keep you connected to your IM servers. This will account for some portion of the things you see running on startup, depending on how many apps you have installed, and whether or not they were written to run as a service.
There are also some, usually older, android programs that existed before "services" were really used.. that basically use triggers to keep reloading themselves. These programs are less efficient, and probably should be re-written to use the official service method of operation, caveat emptor.
Android also makes several modifications to the stock process handling that comes with any Linux kernel, which is already radically different from what most would be used to seeing on Windows as it is. Android attempts to keep commonly used applications running(loaded into memory), but in a sleeping state (using no cpu), so that they may be quickly resumed on request. Android also contains some agressive modifications to the behavior of the OOM(out of memory) task killer in Linux, that seem to cause it to keep applications running until nearly all memory is consumed, killing apps it deems unnecessary only when absolutely necessary. However, Android also supports a methodology of saving the running state of a program, so that if it is killed due to an OOM condition, it may be restarted with relevant data restored, to give the appearance of never having been killed at all.
This functionality is not all to alien to Linux as a platform in general, though Android has many modifications which tend to favor aggressive app management in memory, and less so filesystem cache. This was likely a design choice made to suit the low-speed/low memory platforms Android targets.

Good read.
So then given that...only services running should slow down the phone and not the background apps running.
However, this doesn't really answer the OP's question. If it's not a memory issue...what's causing his slowdowns?
Could be too many widgets on the home screen, I don't run that many but its possible that while in an app for a while, and switching back to home the OS may have to kill a whole bunch of apps to allow it to reload all the widgets on the home screen.
I tested this, and loaded the crap out of my home screens with widgets, and then launched a game. When I exited the game there was a good 500ms - 800ms delay in my homescreens from displaying anything other than the background. However, after it loaded, scrolling between screens looks smooth. The new kernel with highmem support can help this, but I would suspect some crazy widget filled homescreen with a 3rd party live wallpaper (star's configured with too many stars) and all of that combined could be an issue even still. Apple combats this by allowing only one app at a time, they know people will go overboard if allowed.
Well, that doesn't really explain the performance drops. Does the phone run out of RAM, or not? It seems to be snappy again after a reboot, so there must be something.

There's probably no easy answer to this question. There could be IO contention, a runaway process, high CPU usage, a memory leak, shoddy code in some app, etc etc... One would really have to take a look at the whole state of the system at the time the problem is happening to be able to ascertain what is causing the slowdown.
The phenomenon is in no way unique to Android. I'm sure nearly everyone is familiar with the common complaint "my computer is running slow". The reasons that can happen on a common PC are the very same reasons that can be happening here, and unfortunately there are many of those reasons. While in many cases, throwing memory at the issue may appear to solve the problem temporarily, it often is not a permanent fix.
The amount of userspace memory available really amounts to 1 thing and 1 thing only -> the total number of running processes that we can keep totally in memory at any given time. On stock android, slowdown due to an OOM condition should be minimal, since stock android doesn't swap. Discounting any other bottlenecks, there is a practical limit to the number of programs once would be able to run in the memory space that is available. Realistically speaking, android programs tend to be fairly small, so you'd really have to be running a lot of them to exhaust this space. It is far more likely one or 2 poorly written programs are hogging huge amounts of memory (and probably other resources), which is causing constant killing and restarting of other apps you are trying to run concurrently. You end up with contention on the slow flash, resulting in poor performance.
You can't even really compare the Nexus One to the G1 in this regard, because the G1 truly is terribly deprived of memory. Though, the argument in both cases could really be made that you are attempting to run the hardware beyond its design specifications...
Its been my experience that the culprit is usually one or 2 specific programs. Sometimes the best, although inconvenient, way to figure out which programs these are, is to keep watch of your usage habits, and if you suspect something is the problem, uninstall it, and see if the issue persists. Its time consuming but there really isn't any better way to figure it out without using all kinds of tools that android doesn't really provide convenient access to. There are a few apps on the market that help with this but I am not sure what they are called offhand.
Programs that were identified as sources of slowdown for me have been:
Weatherbug
The Weather Channel
Calorie Counter
Locale
SMS Popup
10000
USA Today
National Geographic Wallpapers
CNN News Widget
Streamfurious
Nav4All
Waze
Just about every app with Admob Ads

I'm banking on it being an issue with an app that the OP has installed as well...not the phone or Android. I have only a handful of tried and true apps, and haven't experienced a slowdown even after 150 hours without a reboot.
OP... start uninstalling apps a couple at a time and wait several hours in between to narrow down the problem app.
I can't speak for the OP, but when I was having that problem I had 5 widgets running on my home screen. The Google Search, Sports Tap, Power Control, Calendar, and The Small Weather Channel. Does this seem like too much? I hope not.

the lag vs apps

Now when installed a lot of apps including juicedefender and advanced task killer (set to aggressive when screen off with lots of exclusions) the lag has become more of an issue.
Now tell me whats the logic behind having installed a lot of apps and a lag? Running several apps multitasked will offcource produce performance-dips but just having them installed?
What exactly is "aggressive" on the task killer anyway? Some people say its just bad to kill tasks.
I have the idea that its the widgets that causes trouble, since they actually needs to run in the background all the time. I noticed today that the fancy-widget got stuck on upboot for like 60 seconds, that caused the 4 buttons below to not load properly. Alto the rather useless "daily brefing" seems to slow down.
I dont want to root and hack with sd-hacks now when froyo is confirmed to be released officially soon.
Do you have experice with sertain apps/widgets causing lag. If so, it would be great to make a list of "bad" apps.
PS, I tested the 30-day navigon today in car and it worked with no problems at all. Fix in 2 seconds and right on track.

I haven't used it in a while, but "spare parts" in the marketplace tells you which apps are consuming your processor IIRC. This will obviously give you a temporary hit to your ability to load and run processes but will let you know more details about your phone that you don't already have and the battery use section of settings obviously only talks about what is using your battery but that isn't going to tell you the whole picture.
I am also someone who says you shouldn't use ATK, at least the way you do, but I have it installed and use it a bit differently. What I try to do is kill all tasks after I've used the marketplace or before I do anything intensive (gaming, GPS tracking) and I kill all apps including ATK. ATK will consume processor, battery and will free up memory which then Android uses to open more tasks you don't need (using processor and battery in the process -> repeat cycle). If you need to free up memory 1-5 times a day I think my way will save maybe 15-30% of your battery over a 24 hour period while costing you less than a minute of hassle (too much for some, sure). Again, I only kill after marketplace (because everything opens to check for updates, AFAIK) and before something that will use heavy memory and processor.

Forgot the first part of your question, forgive me. I believe, the reason for more apps causing more lag is at least 2 fold. There are more apps that can be opened when you have free memory (in the vicious cycle I described above). There is also something that might be a bit unique to our phone, and I've only recently read this, it's a bit of speculation so I'm not trying to pass it off as fact but I think it's likely to be knowledgeable on the issue, even if not completely correct. Samsung's internal storage method is an SD card, that allows extra apps to be written to the internal storage but comes with a trade off of lag due to a potential combination of:
slow random-access
bad partition
I think I'm missing an important reason, I'll try to look and edit.
When I initially got my SGS I loaded it with a heap of apps and suddenly noticed the lag and quick battery drain. Problem was I couldn't track down the culprit.
I recently reset my device and was a bit more organized with what I installed. One of the things I started doing was checking what services were being used in the process which you can find under the manage apps part of the system.
So while you can load apps and they may/may not be killed by android or a task killer, the services will always be running - taking up memory, sometimes cpu, network. Things like weather checking, news checking, even email sync are some examples. These services plus any apps you run are I think what starts the lag. You need to be aware of which apps are also run as services.
Yes, there are some bad apps (last Facebook version was found to be a heavy drain) but I think they tend to add up with all the other services running.
As for 'Aggressive' depends on the app killer but my understanding (with the one I use), is that there is a memory limit before the app is killed. Once the limit is reached on aggressive, it doesn't take much before memory is cleared.
One thing to install is SeePU as this gives an indication of CPU, memory and network on the top menu bar. This also helps when the system lags (usually CPU is high and memory is low) and helps to know when to clean (or what threshold to set).
Hope this helps.

Improving performance by removing virtual keyboard

My biggest problem with G1 is not having enough ram. While checking what sits in my ram with MemoryUsage app I noticed virtual keyboard. Since I almost never used it, I killed it. This caused home to reload, but I believe that keyboard has not been loaded instantly.
But after some time, I could see it there again hogging my precious 9MB. Since my phone has usually only like 15MB ram free, this was quite annoying.
After doing some research and BACKUP, since I am rooted I decided to rename the application to see if it will work. The app in question is LatinIME.apk. I renamed it to LatinIME.apkBkp. While I have been there, I did the same thing with LatinImeTutorial.apk. Both files are located in /system/app.
You have to remount it writable first, search this forum for how to do it.
After renaming that file (and maybe killing the app, don't remember exactly) my phone tried to reload home. It failed to do so, force closed and then tried again, resulting in infinite loop.
I rebooted the phone and it worked well, starting normally. Now I have more ram and performance of my phone improved a bit. My free ram stays a bit higher and apps are not so often removed from it.
Overall I am happy about the result and I am looking for more unnecessary stuff to remove.
I am on CyanogenMod 4 btw., so there might be different keyboard apps on other roms.
I have not found anyone mentioning this here, only some tutorials how to change default keyboard, so hopefully someone will find this useful.
If you have any suggestion how to sqeeze even more ram from my G1, bring them on please. (I know of swap, compcache, 10mb hack and keeping low number of apps)

Unused RAM is wasted RAM. The system will kill applications when more memory is needed. Don't worry about it.
And time for you to upgrade to CM6, don't you think?

Idiocy runs rampant at Dream forums, huh? Blame the stupid Advanced Task killer dev for getting all these idiots believing killing apps actually serves a purpose...
Anyway, if the OP is concerned about memory usage and bloat, I very much doubt CM6 is a step in the right direction. Maybe the latest CM 5 is a better option.

Yep, I am very well aware how does it work, but killing the app and loading the other one uses CPU cycles and makes system slow. Especially if it happens all the time as it does on my phone. This is actually the biggest source of laggines imho.
Plus, I am pretty sure, that system apps are not unloaded (some of them at least) or they are unloaded as a last resort. Which was also the case here. I could see other apps being killed (which I did not wanted to be killed) while unused virtual keyboard was happily sitting there.
For the record, I do not use task killer of any sort, does not make significant difference for me and occupies more ram than it saves. So please save that 'idiot' for someone else.
I do not plan to switch to CM5 or CM6, because those need even more ram as CM4 does. Afaik, those roms use hw graphics support which prohibits 10mb hack. I definitely keep 10mb hack on my phone. Did a lot of good to it's speed.
Okay so what setup are you using?
I have tryed every which rom out there since i got into it and i usually only use my phone for browsing youtube music and normal phone stuff and am find these new firmwares to be getting sluggish. Basically i want a lightning quick basic build. I am interested in what exactly you are using.

I am using last version of CyanogenMod from 4 series. That is Android 1.6 based.
I have apps2sd, 10mb hack and compcache enabled. No swap. Was not working for me. I removed all the apps that stay in memory like all widgets etc. The only things that is running in my memory permanently are: SeePU (to monitor my phone), JuiceDefender (to save battery), Battery Left widget and Astrid.
I set my phone to keep Home app in memory all the time, removed all the unnecessary effects in Spare Parts and removed virtual keyboard.
With this setup, my phone performs quite ok. Not as snappy as I would want it to be, but acceptable.
Hope it helps.
I have been using Super-D 1.9.3 with 10mb hack. Removed VPN, VoiceDialer, GenieWidget and some other misc things. Latest ADW instead of Launcher.apk, MusicMod 1.5 instead of stock music, latest 1.6 Phone.apk from Wysie. I also themed my lockscreen and Powertop widget. I has been about 4 months since I flashed it and it hasn't slowed down much at all (and I rarely reboot it). Not a singel FC! Battery lasts me thru the day (I have facebook, twitter and Gmail updating themselves). All in all, its one of the best set-ups I've used. I strongly suggest trying out earlier Super-D roms if you're looking for reliable daily driver (anything before 1.11 should be quite good, 1.11 is when it all went downhill)
Good luck.

You have options.
-Remove apps2sd and use the mtd patch method. That way you cut out the slowest link on the phone: the memory card. With the MTD hack, you can get maybe 150 megs or more of internal space for apps on a donut rom.
-Use the latest version of setcpu since it doesn't stay in memory. You can try an overclock, it will help but shorten battery life some. Maybe 576 or 595 would be enough of an overclock to make it feel faster yet not drain battery like crazy.
-Keep CC on and lock home in memory
-remove the battery widget lol.
=Delete juicedefender and just use the power control widget.
-I usually remove apps that tend to launch on their own, such as the genie widget or the voice search, as well the the VK since I never use those. It's easy enough to write a script or remove them by hand from the terminal. for example, to remove the VK, open terminal and type
Code:
su
mount -o rw,remount /system
rm -f /system/app/LatinIME.apk
-reboot your phone often, and try clearing your cache using cachemate or similar

[Q] protect apps to prevent lag

Hi
I have done the 1-click lagfix that relies on ext2.
I have also installet autokill (the one that changes the internals of the system)
I have 2200 point in qualcom.
STILL I have massive lagg now. It started out well after the rooting, but now its worse than ever. In fact I have even failed to answer a call due to the lagging.
(I have installed Tasker and have 4 tasks set up, i really hope this is not the reason because I would really miss tasker)
I can notice a big differense if I start the dialer and press Home istead of Back. Assuming Back actually kills the process? If I use Home, I can bring it up again in a split second. Using Back and it an take everything from 300 ms to 4000 ms.
I have now started to experiment with Launcher Pro (who some claims to be faster) but this is actuall just a shell and I cannot dedect any differense.
I have tried different presets in autokill, but since this lag is probably not due to lack of memory, i have now set it to "system default".
Is there a way to keep important processes in memory all the time? Like the dialer, contactbook, sms etc? I dont really care if it takes 500 ms longer to start up google maps or facebook, but the PHONE FEATURES must work properly on the phone.
I run a stockrom JM2
hello, as well as the lag fix, I also disabled ui animations and installed autokiller set to strict or optimum and the lag is now minimal for me, it's still there at times but not as bad as you describe.
ironicly i didnt have this problem before lagfix/autokill. It was there so i decided to run the fix (and the qualcom-score is always cool i thought). But now its worse.
Does anyone have experience with tasker as a performance-killer?
