Auto killer and JPH not working so well together. Any help is appreciated. - Galaxy S I9000 Q&A, Help & Troubleshooting

Upgraded to froyo JPH last night and have noticed that autokiller doesn't work so well with it. When using autokiller with all the 2.1 fw's it did it's job and you could see which apps were the empty apps etc. However with froyo the empty apps don't show up and autokiller doesn't seem to be able to perform correctly, currently I have it set to aggressive but I can see my phone go to 70mb free. I have emailed the dev but no response as of yet, anyone else had this issue or know how to fix not being able to kill empty apps ? Cheers.

Why you're using a autokiller app?
The phone got ram to be used. If theres no further ram available for apps android will clear it by itself.
I´m on JPH and there's 192 of 304 MB used.
There's 112 MB free ram!

because auto killer alters androids minfree settings unlike regular task managers that kill everything, also with a bit of use my phone is displaying just over 60mb free resulting in a slow phone.

Maybe you should clean up your phone. I if u installed millions of apps its clear that your phone slows down.

Instead of Autokiller, use OCLF http://forum.xda-developers.com/showthread.php?t=784691
I hate to change the Android default settings for file system and minfree, however after applying the lagfix, absolutely no lag and my phone flies despite several days of excessive use with all possible apps.
If you don't need Lagfix, you could still use the apk for minfree settings and apply on boot.
60MB of free RAM should not cause you any slowness issues. RAM is there to be used, I would want Android to use the entire memory and be efficient in managing virtual memory rather than WASTING RAM by NOT utilizing it for open apps.

Both programs do exactly the same. OCLF even refers to Autokiller as in "using the same names and values for defaults".

With "strict" setting I always have enough ram and still dozens of reportedly running apps. The Android way of multitasking is working really good, it just needs some fine tuning with the Galaxy S. Somehow, the default settings cause too much cleaning up right when you start certain apps, this it feels laggy even though the RFS factor has been removed (e.g. with Voodoo).

I have installed millions of apps, and it is running blazingly fast (using Autokiller to "strict" and Voodoo on JM8). Why shouldn't I? What else is nearly 2GB of user apps space meant for? Why are there so many apps in the store?

OCLF minfree settings, minfreemanager and autokiller all do the same thing - they change the same configuration file that controls Android's memory management tool.
I agree though, that the optimal amount of free RAM seems to be 60M-70M on our phones. The default configuration in the Samsung Froyo firmwares set it to about 40M-50M (the last 3 values in minfree are 40/44/48 by default).
And also, it is a misconception that "free" RAM in Linux is wasted. The free RAM is not unused, but is used by the OS to cache the disks, which is why the phone is faster with more free RAM. On our Samsungs this has a huge effect because RFS is slow and a big disk cache will help it a lot.
You can see this by doing:

5 big Widgets at Homescreen, 12 Apps opened (ICQ, Google Mail, Browser, MP3-Player, Touiteur, Titanium Backup, XDA, Market, ES File Explorer, YouTube and so on), 90mb free ram and the Phone is still running smooth.
Don´t know what you´re doing wrong.

Running JPH for 71 hours now without using autokiller and it has run great without much lag.
Mainly browsing internet, video, music, email and games without issue. And reply messages and calls.

My experience was different. If I just use the OCLF 2.04 and do not tweak with file system and minfree settings, my phone is working perfectly no matter how many apps I load and how long I use (used alteast for 3 days without any lag issue)

I COMPLETELY agree. We are not talking of Windows 9x which could not manage memory well. We are talking of Linux which should work perfectly even when we have several apps running.

I believe the cached portion shows as used memory. We may have to revisit this discussion. As whenever I use memory cleaners, I felt my system went worse if I keep more memory available (except for opening apps which uses the available memory instantaneously). So I doubt free memory (I am not talking of the default available memory on Android) can be used for cache when forcefully freed by these settings/apps.

Completely agree, when I tweak with Minfree settings and the file system to "Deadline" it becomes more "jerky". Others might have different experience, however I strongly believe that while RFS definitely slows down write speeds, default minfree settings and the file system optimization should be optimum for "regular" use.

Every time I flash firmware, I try first without the lag fix, then with the lag fix, and finally, with autokiller, and every time autokiller has helped noticeably.
As things stand at the moment, its one app I wouldn't be without, lag fix or no lag fix.

Working well here. JPH firmware, autokiller set to strict, 91mb free. 3 days of uptime

Making g1 run faster? (10 mb hack)

Hi, I was wondering if I can use the 10 mb ram hack with my g1 with CM 6.0 RC2. I noticed most of the tutoriials are using 4.xx.xx so I wanted to ask before I do it. My phone is kind of slow even though it is overclocked at 576mhz and 64 mb class 6 memory swap. Thanks.

There is no 10 mb hack and won't be. It is not possible with Froyo.
As indicated above there is no 10mb hack and there never will be.
I am currently using the latest nightly and it is super fast and stable. As fast as donut (no ****).
3D Gallery works perfectly and there have been a bunch of small cool features added to the nightly.
I highly recommend it.
Awesome work has been done by Cyanogen and Crew.
ok thanks for the reply guys. Is there any other way to make my rom faster? Thanks.

Of course reduce or remove swap,
android has it's own swap mechanism that causes little ram to actually be least recently used, thus if swap is enabled the phone will be constantly swapping it in/out!
In addition to reducing the life of the SD card its slow. I understand a very little bit of swap *may* allow some edge cases where a *little* more ram is needed or to offload something like launcher that may be configured to stay in ram to work faster.. however you can't forget the speed issue.
Try this enter console on your phone and run:
dd if=/dev/zero of=/sdcard/swapspeedtest bs=1048576 of=64
Note the time it takes, that is the time to write 64mb on a swap out operation.. if it seems too long to wait for a task its too much swap. 12mb is almost acceptable. I just stick to comp cache only. . Upped it from the default 12 to 15 MB since I had one or two tasks that just needed a tad more memory to play nice.
Also what is slow, returning to home? A particular app? I doubt its everything, usually its launcher and there are ways of locking it in home, upgrades to awd, and alternative launchers. These may help.

Thanks for the detailed response! I will try lowering the swap partition, I always thought it would be fast because of the class 6 speeds. Does putting all my apps on SD make it slow as well? Also, returning to home is the main lag I'm talking about as it takes quite a while to see my apps. Thank you!

I have about 3-5 apps that I would like to be running at one time? Should I be using CompCache or Swap? Currently I am on SuperD 1.9.3 WGK. I have been reluctant to run Froyo roms because they are so much more memory hungry in my experiences. My current rom runs pretty fast with a 96mb swap. If I were to fun a Froyo rom, what can I do to be able to run the 3-5 apps and retain speed?

If you are using BOTH SWAP & have applications installed to the sdcard, then it will ****REALLY**** be slow.
With just applications on the sdcard, your speed should be fine.

This is a symptom of launcher being evicted from ram, try the stay in ram option in settings->adw launcher->system settings->system persistent in the more recent versions of adequate (I think included with rc2 if my memory serves me)
It may not be perfect as it will still get killed if a very large application is loaded.
Either you need a launcher that behaves as a good android application, and can quickly reload it's last state, even if it was not in ram when you requested it.. or launcher needs to be considered outside the usual android memory management and to be kept in ram.
These persistent processes are where you may depending on your usage of the phone find comp cache or swap in low amounts (32mb combined is probably the absolute max) may help as they will have allocated ram that is rarely used and not automatically freed as they are persistent..

Thanks for the detailed response! I just changed the adw launcher and deleted my swap partition... It seems to be much slower when pressing home (icons are taking a while to load) so I might just use 32 mb for swap.
EDIT: question, what exactly does ext4 do? I know swap is like external ram, but what does ext4/ext3/etc exactly do? and how much should I put in? I tried googling but could not find the answer. Thanks!

On CM6, nothing. On CM 4 & 5, it was used for Apps2Ext (formerly known as Apps2SD - before Google came out with their own flavor). However, CM6 does not have Apps2Ext. It has been indicated that it will be targeted for 6.1.

[Q] Full RAM after using a some apps... with a little analysis

After fixing some lags with I/O system by using filesystem LagFix I still have a Lag problem in my system and I think it's not related to Samsung.
I think this could be an Android problem.
After a fresh reboot I get 124MB of free RAM.
BUT... every day I need to reboot the phone because after 3 hours it became laggy.
Now I analysed this and read a bit about the memory management on several forums and was able to reproduce the lag 2minutes after reboot.
I just need to use much applications one after another to raise the RAM usage for every application.
When the free RAM reaches 40MB I think the system clears some pieces for using it for the app I now want to use and there is the LAG.
Is there any fix for Android not caching every activity of an application in the RAM?
Now for me Android feels like: Usage -> Full RAM -> Lag
Sorry for the new thread but after 2 hours of research I didn't find anything useful over search function.
Yea, every program should have as much ram available as their size. 2gig for program storage on sgs, so there should be the same amount of ram ;D Anyway, theres still less memory for programs on the sgs than for example in the N1. I'd say there is about 384MB of ram total on the sgs and not the 512 claimed.

Not just the RAM for the apps... there's much more...all mails from internet, all google talk conversations, the wather I checked out from internet with any widget, feels like every interaction is cached into the RAM until it reaches the 40mb mark and after that every interaction on my system is laggy... for example: opening the notification bar needs 2-3 seconds.

Heading out the door in a minute so can't comment on the rest, but I strongly disagree with that part of your statement.
As an N1 owner I've NEVER seen lag like I suffer on the SGS. Never seen the absolute FREEZE in the GUI like the SGS gets.
I'm running FroYo on the N1 now, so can't compare side-by-side to the SGS things like memory usage, but I don't think that's the issue here if you're going to use the N1 as a comparison, despite other users complaining of lag.
You might try Autokiller or the free memory manager app from the Market and see if that improves thing, they'll keep more or less memory free depending on settings. You could test how soon lag comes with default, minimal, and aggressive settings.
I never testet Froyo because everyone said, it's unstable but for me it seems like froyo has other RAM management than Eclair when you said you can't reproduce this problem.
I'm already using a task killer... I have my main apps ignored or excluded and most time there are 2 or 3 apps which will be killed after lock or time or what else.
What's the problem here... if I would use a PC with 512MB RAM and use only 10 small applications, it won't cache everything in the ram until it's full.
Hi, didn't read all the posts, but u should look into the RFS file system, which is samsung proprietery file system. It has a very bad implementation on android (i could be wrong). As for ram, the phone has 512 mb, but 128 are reserved for Gsm/data connection. Just think if you had an incoming call and all your ram was in use, u had to wait for the system to clear up some memory before being able to receive the call physiclly. That would be a long wait.
I could be wrong and sorry for the bad english.

Have you ever tried "Minfreemanager" app?
It can change the minimum available memory level in different app usage.
The device must be rooted first.
Then select "Aggressive" preset and see the result.

DAMN!!! Nice app... it does exactly what I need cleans my RAM so I'll get 120MB and after that loading of apps is much faster than starting apps with Android included RAM cleaning.
It just cleans my RAM like a reboot but without the reboot
This should be a temporary solution until someone finds a better solution or until froyo is released.
I would like to have an application like this with an autoclean option on 2 hours
Guys please,
Getting off-topic here. Here is Android Development.
Not Q&A or General.
Please post in the right section.

Auto killer is better.Its exactly the same as minfreemanager but can be made to apply at boot.Minfree manager resets itself at boot.
I use Memory Booster Lite (free version) app to free up memory, must do that manually but it works very well, if you buy the app it free up memory automaticly.

No, wrong. The reserved ram is in the form of a ram disk, which seems to be a bit oversized. Not really sure why a ram disk is needed at all, personally.

This is the correct solution. the JF* series of firmwares have very bad default settings for killing unused apps. Use this app to set them a bit better and you shouldn't have any problems.

It does have 512 of ram, but some is partitioned off for the phone, so that you can always receive phone calls. Just about every device does this, because users would be more upset if they couldn't pick up the phone until they had closed a bundle of running programs. Don't you think that people here would have noticed earlier if the SGS physically had less ram than claimed ?
As far as the OP is concerned, sounds like you are just running too many programs at once. Its not an android problem, its user error.
Any task manager, but particularly an auto-killer will set you right, although alternatively you could try not leaving every app open when you're finished with it. You think your PC would run ok if you left one game open while you opened another ?

I wasn't comparing a N1 on FroYo to the SGS on Eclair. My comments were in regard to when I was on Eclair, which was several months...FroYo's only been available for a couple of months. What I said was since I'm on FroYo now, I can't compare side-by-side, but my experience with an N1 on Eclair was never any lag problem or GUI freezes.
Anyways, I also suggested you try Autokiller, and you missed that or misunderstood it by saying you already run a Task Killer (which is generally considered a bad idea, but I see you picked up on Autokiller after someone else suggested it. Enjoy.

[REQ/DEV] ROM as allocated RAM

Hi
Dunno if this is possible, but when I think of windows computers back in the days, it was possible to use som of the harddrive as allocated memory.
Is this possible with the o2x? 512mb seems to be a little low on 2.2.2. Guess it will be better on 2.3... but, in the meantime, is it possible from a rooted o2x to use my internal or external as allocated memory...
I got a sh*tload of apps installed, and is down to 75mb RAM available, and it is getting a bit laggish... I've installed Zeamlauncher, and frozen LG 2.2.2 UI, and other unnessacary apps. But I'm still low on memory
Short answer is no.
Longer answer is if you have 75MB free you don't need any more... that's heaps!
There's no point in having a lot of free ram, you only need as much as the next task wants so that Android doesn't need to swap out memory.
Available ram will not affect performance unless it's lower than ~20MB.
Use autokiller (free on market), it can adjust the android memory config settings.
Functional on LG 2x (root needed)
I just thinks the o2x gets laggier and laggier as days go by
at first it was real fast, but then as it got filles up with apps, its getting slower...
got some quite long hangtimes sometimes. espacially when installing a new app.
This was not the situation in the first couple of days. Had it for about 14 days now, and its not as optimal as in the beginning.
Guess I'll just wait for a custom ROM.
It helps using a taskiller + cache cleaner, but only for a short time

I think that Android has a better (and more specific) memory management technique.
Btw the method you are referring to it's called virtual memory and every modern general purpose operating system uses this memory management technique.

Task-killers aren't good with 2.2.2
There's a long explanation as to why, which can be googled.

[Q]Does Quasar kernel support swap?

hi guys,Does Quasar kernel support swap?and how to enable it?
i tried to enable it but failed
and i'm thinking about there's a lot of free space that i never used in /data and /system,so why don't we use those useless space to swap for more ram?
or we can use ZRAM?and how to use it?
we have 512 mb memory, for what you want swap?
actually the ram we can use only have less than 300mb
hmm partitionning SDC should do the job, isn't it ? do "ext" partitions have something to do with that ?
I think there's no reason to use swap, but dxdiag32's idea is not bad... internal memory is quicker than sd...
Regards.
Nah, it doesn't support it.
I did some tests with ZRAM and ZCache back in the LG P500 days and it didn't seem to help with anything so I usually disable Swap support now.
Anyway, you can always mount a tmpfs partition to some applications to boost their I/O operations if that's what you're looking for.

Depends on the microSD card's class. A class 10 is faster than internal memory.
In fact, it's a shame they dropped the yaffs2 filesystem as in non-sequential I/O operations it's the best one.
Class10 is faster? At least internal memory will be less energy hungry... won't be?

Yes, class 10 (>= 10 mb/s write speed) is faster than internal memory.
This is why moving app, data and dalvik to microSD when you have such microSD provides a good boost on I/O operations. There's many folks using the combo CM + S2E + MicroSD Class 10.
As for battery, it's a good question but I bet it should be the same. I/O stuff isn't heavy.
most of us now is using C4 sdcard,at least in China is .so i wanna give us some more performance.my free space in /data partition keep more than 800MB for a long time,and i think more ram can provide us more stable phone.
Beware that RAM works differently for Android devices.
Whereas free RAM in Windows is arguably better than occupied RAM, this is not so for Android. In Android, having RAM allocated is good which is also behind the reason of why we shouldn't use task killers. That being said, we don't really need more than 512 MB of RAM for a heapsize of 32 MB and proper OOM groupings and adj values! Even with an aggressive usage, it's unlikely you'll manage to trigger an OOM (out of memory) throughout your day.
Here's an oldie but goldie article regarding this:

ok got it , thanks knzo

I understand the theory but because of my own experience I do not agree in 100% with You. My previous smartphone was Samsung Spica ( not much RAM ). I used to use my favourite IGO for navigation. It was impossible to succesfully launch IGO if I have not used task killer before.
Without task killer IGO just started and vanished within seconds.

That's because IGO triggered an OOM event and the ROM you had instead of doing an intelligent swipe and killing applications based on certain heuristics, was killing the process responsible for the OOM instead (IGO). It's a flag in sysctl called: OOM kill allocating task.
So in that case, it was just a lousy ROM/kernel. Or perhaps in Spica (old kernel, old android version) there wasn't this setting and the phone always killed the application that made the phone run out of memory. This explains why it vanished after a bit.
Either way I stand correct, there's no need for task killers in a device with >= 256 MB of RAM or properly configured.

Agreed. I still have my old Galaxy Apollo, with 256 MB ram it goes perfectly as it should. In fact, on a careful observation i 've noticed that if we use taskkiller at autokill level at let's say 30 minutes autokill, it will technicall consume 4 CPU cycles in an hour for each app (two for killing, and two when applications like gmail/facebook etc. starts automatically again).. but without taskkiller they may have stay idle, and not used any CPU cycle at all for as many hours as phone is idle. And for battery purpose, it is the CPU cycle that drain, not the used memory !
in my opinion,we only need to kill the apps that use internet in background to save battery.such as Google Maps,once i used it,its services stay in background and after 3 hours i didn't use phone do anything,battery drain 3%,and if i kill it,no battery drain after all
Google Maps and DRM service process sometimes cause battery drains indeed.

i deleted DRM service,and seems it's no harm to system
Lol but do you know what is it function ?

I've seen drm using a lot of CPU as well from time to time. What is it used for and how would you go about removing it?

You can use Titanium https://market.android.com/details?id=com.keramidas.TitaniumBackup
-Go to Backup/Restore tab
-Find by DRM Protected Content Storage
-Click and select Freeze
Now the app is Freeze and the system don't see more!

[Q] ROM with much RAM free

Hello,
I'm looking for a good ICS ROM with much RAM memory free.
I know there are many good ones like RocketRom, but the RAM is priority for me, as I use a lot off apps and I don't want them to get killed every time I exit them.
The ROM may be stock based (best) or even some other type.
Do You know some You could recommend?
PS. They don't have to be fast as hell.
Admin please don't close this thread.
try bulletproofing them and freezing/removing unwanted apps.
Also try to set autostarts off for apps you only want to run on request as well as proper exiting them to prevent running ram.
granted its android that should optimize ram usage which is why amount of free ram shouldnt impact, but yet it does.
maybe you have set dont keep activities to on development settings if so, disable it. lol.
Other tweaking can be done with minfree and oom levels to lower values, stock however they are pretty low.
last random thing I can come up with is less memory footprint apps. Alternatives for ones you are using. Lol. Goodluck!

I have used about 170 apps on my SGS2, now I've reduced them to about 120. I have also deleted some system apps, but the problem is android OS.
Killing apps is disabled for 100%, it's just due to 70MB memory free. The launcher is killing almost every time I turn on some other app (build.prop edit didn't stop it from closing).
Android just uses too much RAM. Fresh ROM uses 400+ MB, that's so much.
That's why I'm looking for some ROM that uses max.300MB. Are there any?
I wish I could have ROM from my xpiera x10, which used max 120MB hehe

These type of threads are not allowed....as the best is up to the individual to figure out, what is best for me, may not be best for you....
