Powertop

Tried searching but didn't see anything already posted....
Cyanogen posted on twitter:
powertop for android binary: http://bit.ly/VfOUN .. it needs a kernel with timer debugging enabled (this is in the CM kernels)
Its a tar file that you download. I tried deploying the files but I get an error:
Error opening terminal: unknown
Here is how I deployed the files......
Code:
# pwd
pwd
/system/etc/terminfo
# ls -l l
ls -l l
-rw-r--r-- 1 0 0 1672 Jul 3 00:47 linux
# ls -l u
ls -l u
lrwxrwxrwx 1 0 0 10 Jul 3 00:49 unknown -> ../l/linux
# ls -l /system/bin/powertop
ls -l /system/bin/powertop
-rwxrwxrwx 1 0 0 286648 Jul 3 00:42 /system/bin/powertop
#

I get the same problem.
My guess is cyan is going to include it with 3.6.1 so we can just wait for that to be released.

ive tried various things too. cyanogen, must use some voodoo to get it to work. chmod 777 the 3 files changing PATH, TERM and terminfo, no avail

From cyan on twitter:
if you can't get powertop to work, try "export TERMINFO=/system/etc/terminfo" first
Tried it, still no luck though.

Screen shot of the problem

GOT IT!
Code:
# su
su
# export TERMINFO=/etc/terminfo
export TERMINFO=/etc/terminfo
# export TERM=linux
export TERM=linux
# powertop

Attached some screenshots...
It suggested "increase the VM dirty writeback time to 15 seconds"...
I think that was part of the sysctl.conf tweak thread. I haven't redone those tweaks since I wiped and put cyan's new ROM on my phone. Interesting.
I wish my dos prompt would work with ANSI control codes so I could run it through ADB...

BTW, the tweaks it suggests are for X86, not Android. Most can be ignored, especially the ones about kernel options.
I included it with 3.6.1 too.

So what exactly does this do?

How did you find this website if you've never used a search engine before?

I didn't find anything specific to android.
Just like a "check what consumes most power"-app.

Does accepting powertop suggestions reduce the speed of the phone?
It is currently suggesting
Increase the VM dirty writeback time from 5.000 to 15 seconds with
echo 1500 > /proc/sys/vm/...
Another one it suggest is
Enable the CONFIG_NO_HZ
Enable CONFIG_USB_SUSPEND
Enable CONFIG_HPET_TIMER
in kernel conf option

A few questions:
I've been running my phone with Open Overclocker at min 528 Mhz / max 528 Mhz. Would it save battery life to put the minimum lower? (I've found that the lowest you can go is "001 / 528" (leading zeros are necessary).)
How do you implement the VM dirty writeback? lmfwtw says "echo 1500 > /proc/sys/vm/...". But what is the "..."?
What is gp_timer? It always seems to be the #1 cause of wakeups by FAR. Next is futest_wait, and sometimes m2m_i2c. Can they be shutdown/decreased?
Is there anything else we can write to the kernel to save power? I found this, http://ubuntuforums.org/showthread.php?t=729644 but I have no idea if any of that is applicable / will brick my phone.

Yeah thats what I found too.
Dont pay any attention to that dude, he likes to play pretend moderator at times and ***** at people for useless posts when in fact his posts are just as useless and adding to the garbage that clutter up threads.
I found this: "Powertop is a Linux command line tool that monitors your laptop (or desktop) and offers suggestions on how to make your hardware consume less power."

I have some other questions as well, but I'll wait. Does anyone know the ones in my last post?

I've been running my phone with Open Overclocker at min 528 Mhz / max 528 Mhz. Would it save battery life to put the minimum lower? (I've found that the lowest you can go is "001 / 528" (leading zeros are necessary).)

Found in another thread...
Do NOT use 128/528. It hurts battery life and the processor. The jump between 528 and the idle frequency is big enough to require extra circuits to be switched on. That does two things... slows down the gain of the processor speed and hurts battery life more than simply running permanently on 528.

I assume going 001 / 528 would be even worse. Hope that helped.

Thanks. Actually, last night after I put it on 001/528, I started having freezes almost immediately. For example, each time the screen rotated when I took the keyboard out, it froze. And when enabling an Alarm, the toast message caused a freeze. And they were 100% full freezes, ie had to take the battery out. After about 5 full freezes, I decided to go back to 528/528 and everything went back to normal. I guess I'll stay on 528/528 hah

[HOWTO] Getting Hero To Run Fast

A lot of people have a tough time with Hero/Sense ROMs. I thought I'd make a guide on what I do to help others out. This is not definitive but it's my personal way of doing things. Comments, tips and suggestions are welcome here. I will update this with some more info as I go along.
I have a MT3G but this is the same for G1.
**Firerat has really comprehensive guides for A2SD and other tweaks. Please check his thread for more info. Also, his post about setcpu profiles is a must read.
First, get a ROM. I'm currently playing with KingKlick's Legend Port and Vegaman's kernel update.zip. This guide applies to any Hero ROM though.
Table of Contents / Overview
First things first
Get your task killers in order (TasKiller, AutoKiller, etc.)
MyBackup Pro or similar if you use them
Autostarts-- one of my favorites. Would love to hear about a free alternative
Droidwall-- free, blocks Internet to apps you choose
Reboot, wipe Dalvik-cache, reboot
Additional steps, Misc, Errata
FIRST:
Partition your SD card. I set a 256MB swap partition and have copious memory left over even under heavy load. EXT2 is better than 3/4.
Flash the ROM, flash the kernel update after. Boot the ROM, go through set up. I always skip signing in at this point as the setup is heavy on the CPU and wait for things to settle before the memory intensive sign in process begins.
SECOND:
Okay, now I see the home screen. Install TasKiller (free/paid) with ADB, MyBackup Pro and kill all the processes except Sense. I highly recommend Autostarts (paid). It handles not only autostart processes but also event listeners and will significantly speed up the ROM. Here are the services I disable:
"After Startup"
Download Manager
My Uploads
Network Location
PC Synchronization
HTC Message Uploader
Peep
HTC Media Uploader
Flickr/FaceBook/MySpace/etc
com.htc.socialnetwork.provider
HTC Widget Download Manager
MyBackup Pro (Uploads your location to their servers at every boot!!)
"Connectivity Changed"
My Uploads
Network Location Service
HTC Message Uploader
HTC Media Uploader
com.htc.socialnetwork.provider
"Application Installed"
PC Synchronization
Pico TTS (why would text-to-speech need to run...)
If you use Slacker.. disable it completely from all "Application Changed/Installed/Removed" categories. No need in them knowing your usage..
"Screen Off"
TasKiller
Notice how (and you can watch with logcat) when an application is modified or installed, it starts up Pico TTS (text-to-speech), synchronization, etc. This is not necessary and a memory hog. You might also be thinking "but I needz muh Facebook" but you don't need it to autostart. These services will load on demand as you use them. Without them, things go a lot quicker.
THIRD: (If you use MyBackup Pro)
Now, I sign into my account with Market, accept the terms and conditions. Once things have settled and I'm able to use the Market I exit the app immediately. I use MyBackup Pro to restore my apps. Version 3 now links apps to Market so they can be updated. Pretty slick despite the fact it logs your location to their servers without your permission. Luckily Autostarts stopped that. Now there's a small catch-- MyBackup messes up the Market database. Easy fix with ADB:
Code:
# cd /data/data/com.android.vending/databases
# ls -l
[I]I summarized the output here for formatting's sake..[/I]
----rwxr-x assets.db
-rw-rw---- billing.db
-rw-rw---- webview.db
-rw-rw---- webviewCache.db
See how assets.db is owned by root and the wrong permissions? This will FC Market 10/10 times. So:
Code:
# cp assets.db BACKUPassets.db
# cp -p billing.db assets.db
# cat BACKUPassets.db | tee assets.db
# rm BACKUPassets.db
Now it will work. The theory is that we can't chown the DB due to an "unknown user" but the other files there have the correct permissions. We use cat and tee to overwrite the clone with the correct contents. It's a hack that works perfectly.
FOURTH:
I then reboot and go to the Market. Install Droidwall (free) and set it to blacklist any app that doesn't need Internet Access. I also install AdFree (free). One site that it doesn't block is flurry.com. This site is used by a lot of applications such as MoreLocale. It uploads personally identifying information about you including your location, phone number, account info, etc. without your permission. I append it to my hosts file afterward. Note that each update with AdFree will erase that entry but I use Autostarts to disable it at boot and never update.
Code:
# mount -o remount,rw /dev/block/mtdblock3 /system
# echo "127.0.0.1 flurry.com" | tee -a /system/etc/hosts
# mount -o remount,ro /dev/block/mtdblock3 /system
FIFTH:
With all the apps now installed that I want to start out with, I go back to Autostarts and disable those I don't want (pretty much all of them). I reboot into recovery mode and wipe Dalvik cache. Reboot, wait for it to cache again and all is well.
Additional Steps
You can easily lock home into memory. *thanks speedysilwady and firerat. Here's how to set this permanently:
Code:
adb pull /init.rc
[I]replace "setprop ro.HOME_APP_MEM ..." with:
[B]setprop ro.HOME_APP_MEM 1536[/B]
[/I]adb push init.rc /sdcard/init.rc
adb shell
# mount -o remount,ro rootfs /
# cat /sdcard/init.rc | tee /init.rc
# mount -o remount,rw rootfs /
# rm /sdcard/init.rc
I will update this as I go. Any comments and tricks like reducing call delays are welcome. Again, this is just how I do things. Hope it helps.

Reserved for the updates....

Reserved for more updates. Just in case.

Don't bother getting kings version just get Vegaman's 0.3 version.
It works a treat and fast as well...
EDIT= and on Vegaman's use EXT2 not EXT4 like you have to do in kings roms. EXT2 is faster then EXT4

Awesome thread! you could also use AutoKiller and Cachemate to keep things smooth as well! =]

Updated OP. I'm looking for the prioritizer script that supposedly gets incoming calls within 1-2 rings... will update when I get it figured out. I have between 40-55MB free memory according to TasKiller when no apps are running.

I agree...and great job thread creater!!!

Interesting! I will try this, how much will the speed increase be?

With what I do, I barely get any slow downs unless I run a lot of apps but I have TasKiller's mini taskbar on one of my home screens and always clear things out before I do something like web browsing, Maps, or games to keep RAM clean.
I'd love an alternative to Autostarts that's free but it is truly great. Blocking listeners causes a huge boost in speed. You will see in logcat when you install an app that all these services start running in the background like Voice Dialer, TTS, etc. That's the reason installing apps seems to peg the phone for a few minutes. Not so when you block those background services.

It's bad to have a large swap and high swappiness.

I haven't had any issues. The swap partition hasn't clogged up or even gone under 100MB left for me yet. Your mileage may vary but it's what I set it to. What size/swappiness would you recommend then? 96MB is not enough, 128MB seemed like too close to the edge of what I need.
I need to make the OP not look like crap...

It is better for the life of your sdcard to have a large swap....because if you allocate say only 64mb to swap...those blocks on your sdcard are constantly being written/read and the rest isn't....better to have a swap of say 256mb so that you are evening out the stress on the blocks more.
I think Wes G or Chris S said this....but that's my paraphrase of it.
Also no difference in speed between a 32mb swap and a 256mb swap. Just depends on your sdcard's class.

If we were talking about computers then swap would be same size as ram, it's better to have no swap at all then to have one

Try Fireat
But for purposes of speed, a large swap partition will get full eventually, and when it does, have fun trying to use your phone. It gets slower because swap has to "dig" through more files to get what you want, the more files it has to dig through, the slower it is. However, you won't notice this if you reboot often (and I guess 5% of Android users reboot daily)

None of newer ones use it for a reason, you would use back-swapping instead(Cc+swap)

[FIX] Bulletproof Background Apps!

UPDATE: Try BulletProofing Apps with my latest V6 SuperCharger Script! Use the following link OR use the link in my signature
I didn't want to risk making the SuperCharge & Bulletproof thread too confusing so I figured it best to make a "sister" thread.
This is a work in progress.
But if this information is helpful, please click the thanks button
HUGE thanks to Feeyo and Bear in NM for helping me figure out a workable solution on locking a background app in memory on boot up.
Feeyo gave me the gist of it but it wouldn't work on boot.
After posting in this thread at Droid Forums, things got rolling - with alot of help from Bear in NM.
Create a Unix script file with no extension (I named it 97oom) with Notepad++ and put it in your i/system/etc/init.d/ folder and put this inside:
Code:
#!/system/bin/sh
sleep 60
PPID=$(pidof [B]com.estrongs.android.safer[/B])
echo "-17" > /proc/$PPID/oom_adj
Permissions: chmod 755 /system/etc/init.d/97oom (same as 10overclock)
You can also do it on the phone itself:
1. Make a copy of 10overclock
2. Renamed it to 97oom (I have a 98governor and a 99complete so...)
3. Deleted the text and put the text you see above
4. Set permissions
Then reboot to test!
You can check to see if it worked with either Auto Memory Manager (AMM) or AutoKiller Memory Optimizer (AKMO).
The bold text in the above code is the process name of the app that you want to protect!
Note: You can get the process name from most process monitors or with AKMO or AMM.
That command "as is" will give ES Security Manager the highest priority of -17.
AKMO shows it as being ignored by the OOM killer
At first it wasn't working on boot because ES Security was not yet loaded in memory.
The "sleep 60 "command fixes that by waiting 60 seconds to execute the command
You can also do this in GScript Lite with this:
Code:
PPID=$(pidof com.estrongs.android.safer)
echo "-17" > /proc/$PPID/oom_adj
This comes in handy for apps that don't load on bootup - just run a GScript for those apps
I suggest you get Busybox Installer and have it install the latest BusyBox (v1.19).
This ensures GScript doesn't spit out ugly stderr: messages.
GScript Tip: 1. Make a file (with any text editor) with the commands
................. 2. Rename it with an .sh extension (example 97oom.sh)
................. 3. Put it in sdcard/gscript folder
................. 4. Run GScript, Menu key, Add script, and click Load file, select a script and Save (leave SU checked)
Even better, you can make shortcut for any GScript.
Long press desktop > Shortcuts > GScript Lite > Select... BOOYA!
As I said, this is a work in progress.
Taming the OOM Killer explains that an app will be ignored by the OOM killer if it has the -17 priority.
The problem is that Android will still shuffle it's priority downwards like it does with any inactive app.
If that happens, then the app reverts to it's usual priority.
This is why ESS will lose it's -17 after a couple of hours. It just sleeps ALL the time.
My thinking that if a more active background app, such as an SMS app or a music app is given the -17, it won't lose it's priority at all.
Feedback with results is more than welcome!

No need to set a variable, just use back-ticks:
Code:
echo -17 > /proc/`pidof [B]com.estrongs.android.safer[/B]`/oom_adj
Although that may be a little too complicated for some people to type in. Best to keep it simple I suppose...

That's pretty cool.
I figure most people would copy/paste the whole thing and replace the process name.
So maybe the back ticks wouldn't be a big deal.

That is why I try and avoid putting any code I use on forums. Someone who actually knows what they are doing will always come along and whack me ;^)
Seriously, good work Zep.
Craig

I don't mind.
That's all a part of learning so it's always good that there's somebody around that's "smarter" at something than me.
For example... this script I'm trying to get working for supercharging stock phones...
On custom roms, CM and FroyMod at least, I'd modify /system/etc/rootfs/init.mapphone_umts.rc
I flashed stock telus 2.2 and the path seems to be just /init.mapphone_umts.rc
I don't see rootfs anywhere
But there is a rootfs is mounted
To mount as rw, "mount -o remount,rw /system" doesn't work
In gscript, I'm getting "sed not found" errors too.
grrr...

how well do you think this would work with handcent? it's a little laggy to load up on my phone, but i want to try it out more. will keeping handcent in memory eat up ram that i need otherwise? and do you think it will be active enough to keep it's -17 after a few hours? thanks
edit: i was trying it out, it disappeard from processes withing a few minutes. oh well, maybe it doesnt need to be running anyway

Did you check with AMM to see if handcent had the high priority or if it really got killed?

ya, i checked. it was set to -17, then next time it refreshed it was gone. then i opened handcent, went back, and the process had a different pid, not oom level. oh well

damn
Maybe some apps are too prone to get killed off and the only way to keep them alive is with multitasking friendly minfree values

Yes, I've seen the same happening with the stock SMS app. I did not receive SMS anymore so I decided to look at it a bit closer (using adb logcat). I started the SMS app, noted down the PID and set the oom_adj value to -17 using adb shell. A few seconds later it was killed. Setting the minfree values back to system default allows me to receive SMS again. Also whatsapp, gtalk and push mail now work reliable. With high minfree values I could see in the logs that, when a message arrived the app is started and immediately killed afterwards. So, I was never notivied that a SMS or whatsapp message had arrived. With default minfree values it seems to work more reliable.
But it all depends on how you use your phone, I guess. I'm using it as my communication central and don't want to miss any message. If you use it more as your mobile gaming or surfing device you might still be better off with high minfree values.

I agree.
That's why I made 6 different profiles.
The multitasking and balanced 2 settings, for example, will leave you with more free ram but are actually more background app friendly than stock google/android values.

I see. I did not realize that. It seems I've been reading your post too superficially.
I'll give those settings a try. I've just lost another SMS (this time with the default setting)
If I can't get this under control I might go back to CM6. I understand this is not as memory hungry as CM7 is.

Well, handcent is a giant pain in the ass.
I'm running stock telus froyo and the thing doesn't even stay loaded and I'm not even doing anything.
I run it.
Try and bulletproof it with a gscript (and sometimes handcent is even killed off if I take too long opening gscript lol)
The script won't even change the priority of hancent.
It stays at an 9 or 10 in the content provider grouping.
But the thing is a pig anyway.
20+ mb of ram used up and the app itself is close to 5 mb.
Maybe froyo has a reason to not like it? LOL

very very important and informative post!
thank you!

I did it, and after reboot stock sms app (com.android.mms) is killed, I cheched in AKMO, and that fix didn`t help, so I set default minfree values in AKMO (although the previous settings weren`t so strict)

Ok, first off, I am a UK Milestone, running Cyanogenmod 7 RC4. I am trying to raise the oom_adj of COM.ANDROID.MMS and I just used the method zeppelinrox posted instead of the proposed alternative (though I did try that too) and the startup command seems to do nothing. So I decided to try the GScript way and I get this:
Code:
stderr:
stderr:
stderr:
stderr:
stderr:
stderr: cannot create /proc//oom_adj: directory nonexistent
stderr:
stderr:
stderr:
I have never used GScript before and maybe I am doing something wrong here, but I am running it the script as superuser, I have exactly what zeppelinrox has (except a change for the messaging app process name) and I am at a total loss here. Other methods worked fine on my RC3 and keep Messaging as a "Foreground Group" app, but in RC4 it is an "Empty" and that means it will likely get killed a lot. I am using stock minfree values, just using AMM to check oom. I don't want to be missing texts, so any help would be greatly appreciated. Let me know if you need anything else.

You get that "directory nonexistent" error because the app was already killed so there is no PID anymore.
I suggest you get Busybox Installer and have it install the latest BusyBox (v1.19).
This ensures GScript doesn't spit out ugly stderr: messages.
I finally installed CM7 for the first time and RC4 at least does have the option to lock messaging app in memory.
It's sitting in the foreground with a 0 priority

I thought that maybe it was killed already also, but I opened Messaging -> checked System Panel to ensure it was running -> ran the GScript (which failed as noted before) -> and checked System Panel once more and it was still running. Maybe I am crazy here..
I am using the "Lock messaging in memory" but "Messaging" process is still killed by the stock manager, is it still alive in some separate process? It certainly is not 0 priority in Foreground, still sitting in "Empty" at something generally over 4 priority.
I will probably just switch back to the previous build as all was well there, though I would like to be able to keep up with the newest features.
Thank you for the Busybox link, I will try that.

That's strange.
Maybe that setting needs a reboot?
I remember seeing messaging in content provider earlier and then I was actually surprised to see it in the foreground.
I actually checked to see if I still had the 97oom file in the init.d folder but it's not there.
But it should be immediate because if I uncheck Lock messaging in memory, it gets instantly killed.
I run it, check lock messaging again, and AMM shows it in the foreground group again.
Stderrs... now I dunno what's going on with that
GScript was working perfectly in stock Telus rom without stderrs after installing busybox (to get certain commands to work).
But in CM7, after updating busybox, stderrs all over the place.
Now I have to figure this out.. those stderrs are annoying as hell

What am I missing here? I'm looking at my CM7 Milestone right now with the "lock messaging app in memory" selected. And the messaging app is sitting in "background". Then I set the oom_adj value to -17 and a few minutes later messaging is gone. I'm starting to become desperate.

Please help: big lag issue

Guys, I need a help. Tried everything, but still facing big lag especially when I click on dialer, contacts or messages (waiting couple of secs until they show up). This is more obvious when I click right after I 'woke up' my phone from deep sleep.
I'm using stock 20b with Iodak v8 kernel (tried v9 as well, but due to bluetooth and fm radio issue on stock, reverted to v8). Also, I did everything what I could found to improve performace: disabled and then deleted MLT, did a full wipe of everything (clean install), installed only apps that I need, turned off 3g, data and gps (only WiFi is on), installed Greenify and so on..
My current setup of kernel is following:
Governor: interactive (tried ondemand, but was even worst)
Max: 1600000
Min/Max Screen Off: 760000
Scheduler: SIO
CPUQuiet Power: userspace (noticed that only 3 cores are online instead of 4)
I appreciate any help, but please, don't tell me to search, 'cause I did. As for the other custom roms, I tried CM, but I prefer more stock, mostly because of Gallery, Polaris and FM Radio Apps.
Guys, is there any way to fix this lag issue? I don't care much for the battery, since this lag drives me crazy.
Thanks in advance.

This is "normal" for system apps. Download custom apps from google store like ExDialer,GOSms.. That will resolve your lag.. When you install those apps from store, use titanium backup to freeze stock apps(dialer,contacts,messages).

Thanks guys, but neither of these two options helped. There's some improvements, but still pretty much laggy.

Think I found out what causing lag: synchronization. Every time when phone is synchronizing, everything is so laggy, otherwise is ok. Following accounts have sync turned on: Skype, Facebook, WhatsApp, Twitter and Google.
Does anyone of you have experienced similar problem? Is there solution for this?

I have all those apps running in my phone, but I did not face those lags.
But ya I did felt those lags when I'm still using stock JB OS. Stock JB from LG is sucks man, you should instal another ROM.
Currently I'm using CM11 (Kitkat 4.4.2 based), its lag free and have more free RAM. (around 350 - 400MB). :good:
The difference is like heaven and hell compared with the stock ROM (I only have 150 - 200MB Free RAM).

The ROM can make a difference, but it has nothing to do with "Free RAM". I wish people would stop perpetuating this myth.
Free RAM is wasted memory on an Android device. Unless you are getting below about 50MB there is not a problem as the device is designed to use as much as it can and then swap it out automatically.
I agree about CM11 though. I'm running the latest nightly and the only problem I have is the delay in waking when you press the power button

Well.. Sorry for my false statement and thank you for correcting it
4X HD is my very first android device. But that's what I really thought after I flashed the CM11.. Its like whoa, more free space on RAM, and it feels like I'm using a new phone

RAM: What it is, how it's used, and why you shouldn't care

Well, I’m afraid that I’ll be forced to get back to CM (used it once, but missed some apps such are: FM Radio, stock gallery app (couldn’t find good replacement that synced photos with google acc) and Polaris Office – these apps I use on a daily basis). Anyway, before install CM, I’ll give one more try to Stock.
I did what @ottomanhero told me, and that actually helped. But, since I used Trickstermod to tweak governors, after every single reboot, stock values would be back, so I had to use init.d script, and there comes a problem.
Here is what I did (followed instructions from Iodak's OP):
- Using ES File Explorer created folder /system/etc/init.d and set permissions to rwxr-xr-x
- Created new file in init.d folder and name it 1script (used Note++ instead of Windows editors to avoid leaving an extra space at the end of each line or an invisible invalid character)
- Then added following commands:
Code:
#!/system/bin/sh
echo "70" > /sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load
echo "70" > /sys/devices/system/cpu/cpufreq/interactive/midrange_go_maxspeed_load
echo "60000" > /sys/devices/system/cpu/cpufreq/interactive/min_sample_time
echo "20000" > /sys/devices/system/cpu/cpufreq/interactive/timer_rate
echo 200 300 400 450 500 600 > /sys/devices/system/cpu/cpu0/cpufreq/gpu_overclock
- and finally set permissions to 1script rwxr-xr-x and owner to root group to shell
So, that should be it, but didn’t work for me. Then, I installed SManager to check what’s wrong with the script, and it stated that with first 4 lines error is: no such file or directory (which is strange because exactly that's the path), and for the last line is stated: permission denied.
Did I miss something? Apologize if this question is too noob for you guys, but I’m running out of ideas.
Thanks all for your help.

Vladimir

Free RAM is NOT wasted RAM.
It directly effects smoothness of the phone.Why do you think android would have Out Of Memory values if it was created to just fill up the RAM with only apps? It still needs some RAM free for caching.

I think the script didn't execute at boot due to last line, you forgot the quotes.And while using Smanager you gotta tick "root" or else it won't run.Try this one

Well, you were right about the quotes (now, the new values are set), but as the other 4 lines, they still have the same error: No such file or directory, and all values are stock.
Do you have any idea what's going on? Why did it work for one, and didn't for the other lines?

Of course you need some free memory, but not hundreds of MBs of it. I notice that you pointed the same XDA quote that is used and linked to by lots of different sites when this is being discussed. To use someone else's quote - better written than I could do so myself;-
In the most simplistic terms, here is how it works, and why "free RAM is wasted RAM," but also, why you don't want all RAM in use at any given time.
If an application is not in memory when you try to open it, that application haa to be loaded into memory, thus triggering a "load time." Having the application in memory (prefetched) prevents this load time and has the application load near insantly. This is why a modern OS will preload our most commonly used applications into memory. The more memory that you have, the more applications that can be preloaded, the smoother your device will run. Clearing this memory gives you no immeidate benefit, and will actually slow your device. Idle applications in memory consume almost no resources (CPU cycles, battery power, etc.). If an application is consuming resources, that means that it is doing something. Closing it will only force the application to re-load. Using a task killer for this purpose will cause a "boxing match" where the task killer closes the application, the app reopens itself, and back and forth. THIS will consume resources.
However, you want to have some memory free. Your devices will not have enough memory to preload EVERY application, so it has to guess based on your actions. It needs to have enough memory available to quickly load an app that you may want.
Let's say that you want to load an application that requires 256MB of RAM, but you only have 128MB available. This means that the OS is going to try to clear 128MB of RAM to accomodate your app, and as your app loads, will try to clear another 128MB to return to its previous state. This clear/load/clear causes a longer load time and more slowdown than just loading an app not already in memory.
So, the ideal situation is to have most common apps in memory (pre-fetched), but enough memory available to handle 1-2 common apps that are not already pre-loaded. Touchwiz (Samsung) devices allow you to clear memory from the task manager. My S2 had about 870MB of user-available RAM, and if I trashed all apps, it would go as low as 300MB in use. This may look cool, but it is a complete waste of resources, and the OS is simply going to re-load those apps over the next 2-3 minutes anyway. And if you use a task killer to keep your device idling at 300MB of available RAM? This is simply going to slow down the device, harm the battery, and give you the same memory performance and availability that you would get with an HTC G1.

As the OP was stating that "I only have 150 - 200MB Free RAM" with the Stock ROM, that is definitely NOT what is causing a lag issue. If you have that much free memory (before Android goes caching stuff and not declaring it of course) then you are absolutely fine on any Android device there is.

Maybe your partitions aren't mounted.I took these lines from pimp my rom init.d script.Create another script but it has to come before the governor tweaks script.
#!/system/bin/sh
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier =0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodir atime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodir atime,barrier=0,nobh /cache

For example, name this script "93Mount" and name the governor script "94Governor" so the mounting script will be executed before governor script.

Well, I did like you said and here's what I got:

failed: No such file or directorybh on /data
mount: mounting atime,barrier=0,nobh on /cache failed: Invalid argument
Any idea?

For the People who want Stock Gallery on CM and hate Aosp Gallery like Iam, check facebook offical cyanogenmod. They send a link to their new gallery next. Its in beta stase, so its not avaible yet. But if its stable itll be in play store. Its like the stock gallery app. Very beauty

Well try this app https://play.google.com/store/apps/details?id=com.stericson.remount&hl=tr
EDIT : check this link out. http://forum.xda-developers.com/showthread.php?t=1381188

I'm not sure it's the right track or not, it does happen to me quite ago.
The problem is the SD (my case, luckily it's external). The system try to read files from card but it got error thus try again => laggy
I removed the card and it's alive. Try to check your internal sd. hope that help

App didn't help, I got the same error. Never mind, I give up Will use Trickstermod after every single reboot until finally find solution. Thanks @ottomanhero for all your help.
@GalaxyVolvoZ that app looks realy nice. Finally a good replacement for Stock Gallery.
@klbterminator I don't have any problems with SD, at least didn't so far
Thanks guys.

Is pokemon go working on this device?

Hello,
As any of you made pokemon go work on the Samsung Galaxy S I9000?
I have installed an APK from the internet because it has yet to release in my country but it stuck at the niantic logo and nothing happen, it close itself after a fews minutes.
I have the omni version 6.0.1 on my Samsung Galaxy S I9000, so if any of you know how to make this game work on this device, it would be great;:victory:
If you have some free time, please test it on your Samsung Galaxy S I9000
Thanks you

Same here,
even got the app from the store but experience the same behaviour. After seeing the Niantic logo for a looong time either the app closes or the phone restarts.
Phone is a GT-I9000 running Android 4.4.4 (Cyanogenmod).

Same behavior,
ROM -- Omni 5.1.1 with max Bigmem.
Looks like this game requires at least 1GB of RAM (some sources even say 2GB) so I don't think it's going to ever run on the 1st galaxy.

If someone know how to make it work on this device, please share, i really want to play this game ;(

I'm currently running CM11 on my phone, and after I used a sd card to create a 1gb swap partition i got it running, although very choppy. Now I'm looking for a lighter / faster rom, possibilities to overclock or generally ways to increase performance. Tried NOMone Resolution Changer, which helps a bit, but still not that great. Any ideas from the experts here?

I'm running 11-20250901-SNAPSHOT-XNG3CAO3G0-galaxysmtd and got it to run, albeit unplayably slow and unstable. What I did was creating a swapfile in /sdcard0 (first 2GB, after checking free when the game was running lowered it to 800MB). Well ... at least I could reserve a nickname until I get a phone that can really run the game. Thanks for the idea Mirazuul.

How to create swap file on cm11?

open up a shell via adb shell or a terminal emulator on the phone, then
Code:
[email protected]:/ $ su
[email protected]:/ # dd if=/dev/zero of=/mnt/media_rw/sdcard0/pokeswap.file bs=1024 count=1000000
[email protected]:/ # mkswap /mnt/media_rw/sdcard0/pokeswap.file
[email protected]:/ # swapon /mnt/media_rw/sdcard0/pokeswap.file
you might need to adjust paths. as for the size of the swapfile, 800MB (count=800000) works too. haven't tried anything lower.

Trying to make Pokemon work on GT-I9001 - tried to run on CynagenMod 10.2, now using this ROM with CynagenMod 12 - but having the same problem with it as above posters - white screen with Nianatic logo for almost half minute, then black screen and return to phones main menu. I made a bigger digging and I see that Google Play and Google Services are both not working on the phone also, making the similars problems as Pokemon. Gone over every tip in this article... Anyone have idea how to solve this?

Actually I found a way to run it without creating a swap file and somewhat playable (still slow though, about 8-10 fps). You'll need to use GLTools to tweak your OpenGL to make the textures worse and to lower the rendering resolution twice. Videos on YouTube which show how to run pokemon go on 512mb device pretty much show what needs to be done. For example this one: https://www.youtube.com/watch?v=aA0hnFb2APQ
You may also want to activate BigMem on your device (kernels in Omni 5 ROM builds support it for example) to get the most free mem possible.

I am new to all but com want to play this game I have started to work in less than a week I roteado my gt- i9001 and I've put the 4.4 ( all without knowing anything ) . I cost me his stuff and do not want to give up for a problem of RAM. In tonces , if anyone knows how to resolve it that says please and leave well explained , for a beginner like me can understand , thanks.
PD-.I'm spanish boy.
