[HowTo] Tweak your Archos

Hi,
recently i came upon a thread with someone asking :
how to optimize the archos to be quicker ?
As this is propably a question many people might ask (even I still do ) I thought about creating a thread about. This is not just to answer his question but also for all u nerds out there to corrent me - as I might be wrong in some points AND to gather new options to speed up the device. This is what i have learned yet...
Anyway all of the things I list here require root as far as I know. So get your device rooted or abandon the Thread
ALL THINGS IN THIS THREAD ARE WITHOUT WARRENTY - SO IF YOUR DEVICE STARTS MUTATING INTO A DOG HUNTING YOUR ASS FOR NEW FLESH - BE WARNED
Memory Management:
Introduction: HAVING FREE UNUSED MEMORY ON ANDROID HAS (nearly) NO ADVANTAGE (exception having 0 memory also fu**s up the device -> 1. )
All of those methods wont make your device faster in the meaning of really getting faster in speed... as android already has a quite good memory management.
BUT if u get more space in memory your device can keep more of the apps U LIKE in memory (being inactive according to app lifecycle). This will make them get called faster next time u use them and your device will "feel" faster and more responsive.
1. What should work on all roms are the "minfree" settings -> meaning when android really kills apps - depending on free memory (if u don't know what is mean by - search for the "App Lifecycle" of android)
You can try setting those to the values mentioned by sibere (scroll down) or try finding your own settings. There for u can use any app like "AutoKiller Memory Optimizer" just serach "memory optimizer" in the market.
KEEP IN MIND - you may play a bit with those settings - BUT still u should know what u are doing if u use it!
LOW: If u set the values to low the device will kill apps very late keeping much of them in memory this might make you device get slow. If there is too less Memor fo a "new" app or another process just need more memory while running it has to close down other processes before memory can be allocated.
HIGH: If u set em too high u kill most apps instantly - and your device will get problems and might get unstable as far as i understood.
2. Try gettign more "free" memory by disabeling services - as those got the highest priority they wont get killed that fast by the memory management. For checking u might get an app like "TaskManager" wich lists all running processes.
Just check out what takes your memory and disable those u dont need.U can disaable them by using "Titanium Backup" disable app / uninstall em / or just uncheck their autorun by using a programm like "Autorun Manager". Remember if u just disable the autorun they might (re)start later still.
3. Use a low sceen count in your launcher and keep the widget count low. This is related to 2.) as most widgets run a "background service" to update itself / pulling information (e.g. a waether widget getting latest conditions, a calendar widget keeping connection to your calendar app,...) - each widget took at least 8MB memory when i checked with TaskManager - "greater" widgets like "Fancy Widget (sense like clock and weather widget)" sometimes take up to 25MB
4. DONT USE A LIVE WALLPAPER (live wallpapers use MUCH memory most 20MB-40MB - either they get closed down all the time - or they just reside in memory taking the memory u wanted to use for keeping other apps active)
I also noticed that the App Drawer got "much/noticeable" slower in every Laucher I tested while a live wallpaper was active
5. DO NOT USE A TASK KILLER (remeber the introduction!!! - and think about it yourself - if at least 20 ppl ask why - i write this down here )
6. SWAP / COMPCACHE (can be activated through UD config) - this is a really hard question - those methods extend your memory but the memory u gain is MUCH slower then the internal memory. So again u have to decide and try out if it helps u or it doesn't (I used em long time but never realy felt a big advantage of. Compcache even made my device feel slower and i got more FC's most time - also I tried to figure out how the memory management uses this "memory". But i din't find a clear answer yet - as some ppl mentioned that "inactve apps" wont get swapped - need some clear source... Anway in general those 2 should increase Multitasking capability at cost of speed.
7. FUDGESWAP
- noting yet - its GINGERBREAD only - so we have to wait...
FINALY: u have to decide on your own what u really NEED to run "simultaniously" (I personaly rather have less widgets and run background services like growl, eventghost, tasker) but u can count it yourself by checking back with taskmanager and having in mind your archos (GEN8) just has 256MB of internal memory.
CPU Manaagement:
8. (UD) If u got Urukdroid u can try setting your CPU Governor to another value like:
"Interactive" is more reactive than "on demand" (-> SIBERE)
9. Try an OC (OverClocked) Kernel -> get it in the Urukdroid Dev Thread (I wont link any here as u should know what u do and wich u choose!)
BEWARE not all devices can use an OC Kernel (sadly mine can't) but try it out...
10. Try overclocking your device with the Milestone Overclock Utility. This overclock method is based on a module insert. Again this just works with root.
OVERCLOCKING:
Each CPU is different -> each device is different and can handle different maximum speeds - this is related to the former position of the CPU on its waver while production...
So u have to try out what your CPU can handle safely - so it might happen your device will refuse to boot after u flashed a kernel or set some permanen OC values. Keep a BACKUP or reflash old kernel...
In general u normaly can't brick your device by overclocking as the CPU overheats -> safety function of the CPU stops it -> the device resets itself before the CPU get "burned" (hope this also aplies to ARM processors )
Other:
11. The Launcher: I tested out much lauchers already: ADW, ADW EX, VTL, Laucher PRO, Zeam Laucher, GO Laucher - most of them seem to be eaqual in speed and more differ in features (event Laucher PRO is still the fastest on my Wildfire [but development stopped some time ago], GO seemed to be a bit slower imho) - take any of those but avoid taking some over exagerated 3D'ish laucher like Regina, SPB Shell, Claystone...
12. Apps like "AutoKiller Memory Optimizer" have additionaly features to "optimise" the speed,... u might test those out but I didnt notice a difference most time. Still keep in mind - u should know what u are doing
13. Ok - u may want to hit me for that:
It's more a cosmetic thing - but I recently used UOT Kitchen for theming my framework and used the fly-in animations - and they feel much faster then the default animations just try it out... keep a backup of your original framework for reverting.
All the following Tweaks are mentioned by sibere (credits go to him and propably some other people)
echo "1536,2048,4096,6144,8192,10240" > /sys/module/lowmemorykiller/parameters/minfree
(this is related to 1. ; 1MB = 256 => valueas above are 6MB, 8MB, 16MB, 24MB, 32MB, 40MB)
to enable cgroups cpuacct:
mkdir /acct
mount -t cgroups -o cpuacct none /acct
mkdir /acct/uid
to change ioscheduler:
cd /sys/block/mmcblk1/queue
echo "deadline" > scheduler
cd iosched
echo 1 > fifo_batch
These are lost on reboot so if you wanna keep them, add a script to /etc/init.d
Finaly I also have patched the sqlite library. If you want the file, let me know. It boost a lot SQL database writings. See this thread http://forum.xda-developers.com/showthread.php?t=903507

Will ask him to comment on "cgroups, ioscheduler, and sqlite" as im not sure if they work with all rom versions / neither how they work exactly.
THANKS Sibere
EDIT:
aditional threads with tweaks
- Supercharger
- http://forum.xda-developers.com/showthread.php?t=1227269
BEWARE I HAVEN'T HAD THE TIME TO CHECK THEM OUT YET AND DIDN'T TEST THEM
SOME OF THEM MIGHT NOT WORK AND PEOPLEARGUE ABOUT THEM (e.g. the "debug.sf.hw =1" is heavily discussed)
IF ANYONE KNOWS MORE ABOUT THOSE OR CAN HELP TESTING IM HAPPY TO LEARN MORE ABOUT

Hi.
For a full reference to cgroups, you may read the cgroups documentation from the kernel.
Basically, it provides process aggregations in the Linux kernel, mainly for resource tracking purposes.
deadline IO scheduler has been used a lot for SSDs and proven to be quite adapted to flash memory.
The minfree settings set here are pretty much optimised by me for the archos. It gives you a good balance between available cache and free ram . Android starts to complain when the free ram drops below 32Mb. with these settings, the OOM task killer will try to maintain a free ram level above 32Mb. You DON'T need a task killer. It will just use precious ram resources and will mess up with the android integrated task killer.
Those settings are reset on boot, so you may add them in a script added to /etc/init.d/ directory.
SQlite optimisation is of great help and I already posted a lot of information about it when I posted the tweaked file. Please refer to this post. (You'll have to look for it, it's somewhere in the dev thread )
Enjoy your optimised archos!

Thanks guys, learning new tips.

Nice! Good tips. Thanks.

Very usefull reading, thanks!

thanks for the tips ! cheers!

Hello, I am JustLoveJoy, I am an up and coming developer, although I work very hard on my phone right now, my gf has gotten an Archos 8 G2 4GB tablet and I have it rooted but it constantly gives me some issues. Finding this thread, I have to ask, can these or any tweaks be applied to her tablet? is there any source code on github or somewhere else? I mainly wish to get her to be able to do her Farmville on it. I'd like to get on to the development boards with a custom rom for it but I need someone with a little experience to point me in the right direction for that. Thanks So much for starting this thread!

hi i just want to try to root my arnova 7g2 bit i don't find a straight 3d on xda. you clan indicate the right street

did you notice that crow (CM7) for Gen8 was released ?

still nothing for developing for the Archos 8 G2 4GB? If I can get adb shell I would be happy!

Thanks

Thanks for the great post! I still have one of these!

[TIP]Improve Sense performance over time

Many of you have probably noticed that performance of Sense roms degrades significantly over time. At least for me, it gets painfully slow after only few hours of usage and I have to reboot to restore the performance.
It appears that cause of this is lack of free RAM, because a lot of applications are still sitting inside RAM even after you stop using them and Sense needs A LOT of ram. A good way to fight this is to tweak settings of android's built in task killer, so it will kill more apps to free more memory for sense to use.
One way to do this is to:
1. Install "System Tuner" application (free on market)
2. Inside application go to Memory screen
3. Click presets and select "Aggressive". If performance is still horrible after performing this tweak, try switching to "Very aggressive"
4. If you wish this tweak to persist after reboot, select "Boot Settings" and enable "Re-apply memory limits".
That's it. For me it changed Sense roms from unbearable to snappy. It will of course significantly reduce multitasking ability of the ROM, but for me it is worth it.

So do you think there would be a better way to go about this then to close certain apps that aren't meant to be closed? It seems some
developers suggest not to use task killers because of this very reason. Would there be any other benifits or negatives in doing this?

You're not using task killers, but just tweaking android's built-in task killler, which means that system apps are safe.
User apps that are not meant to be closed usually provide option to enable notification, which makes them foreground apps and that means that they will probably never be closed.

I was thinking that by switching it to "very aggressive" you may end up closing tons of system apps that aren't meant to be closed. Thanks for clearing that up.

[q]very high system ram usage[lollipop][5.0][lrx21t]

Hi ,new user on xda
i have a nexus 4
running completely stock 5.0 LRX21T NO ROOT
i have noticed very high ram usage on 5.0 as compared to 4.4 after the update
normally had ~1gb Ram free but now only ~500mb remains free
on ruuning applications screen,it shows
system-~750mb
apps-~600 mb
why is system using so much Ram,wasnt the case in 4.4...
is it bcoz of ART ?
is this normal?

same problem..on my nexus 4 after 5.0 update
After reboot, system ram usage stays low (read 100 to 150mb) for 1 to 2 days.. But suddenly shoots up to more than 1gb.
Does anyone know the root cause.

I think i found the root cause to this..
In Settings -> Sound & Notifications
change the setting When Device is locked -- Don't show notifications at all
By doing this, the system ram usage never shot up above 200mb for the past 2 days for me.
previously I had to reboot my device every night before going to bed.
I will further observe if this is the root cause and revert back.

art by default use more ram than dalvic to run applications so this might be normal for you. on top of that there is some memory leak found in android l.
the important thing to now is how android manage ram. when you open an application it is loaded in the ram. whether you close the application or let it run on the backround android does not clean the memory occupied by the application until it has to. android LMK (low memory killer) clean the ram memory occupied by a program denpending on the priority id of the app. for example system apps (system ui) has lowest priority so LMK never kills that app. other apps have different priority. an application that runs in the backround (facebook messenger or whatsup) have lower priority than a game so when android need more ram it will empty the ram occupied by the game first and if there is more need for ram it will later empty the ram occupied by the backround app.
Long story short android will handle the ram as it sees fit. unlike windows, android will keep the memory full so apps can be launched faster. the problem is that android l has memory leak so you need to reboot your device every few days if you feel it starts to have some lags.
apps like task killers do more harm than good in terms of performance or lags. also facebook and facebook messenger are very badly written apps so they will consume a lot of memory. also antiviruses (especially cm security) are responsible for lags and memory leaks.
hope i helped you somehow understand android and find your problem (if there is one)
P.S. sorry for the long post!!

This is why Google needs to give us an extended power menu. I understand they say it shouldn't be necessary under normal circumstances, but I consider every single nexus update to be a beta, of sorts...and we all know how buggy betas can be from time to time. They're very unpredictable, and you never know if you'll need to reboot. Saying it's simply never necessary for something that is basically beta is just plain egotistical as hell.

my philosophy is that when you buy a nexus device, because it is a very simple os without the good stuff that lg/sammy or any other oem android manufacturer put on their phone(i am refereeing to the shortcuts power menu or toggles and other things that make your life easier and not the whole change of the os like touchwizz) you have to root so you can do your own small changes as you see fit (and fortunately for me i live in europe where there is a European law that states that you have the right to do whatever you want to the software of your device an be eligible to waranty).
So if you root your device you can do everything you want. for me on kit kat it was xposed and gravity box. on android l, yesterday i installed simple aosp.
In my opinion pure android with a twist is the way to go! and of course a custom kernel for better battery life and ad free for no ads!!
P.S. a quote by a fellow nexus user: A nexus without root is like an angel without wings

I do have root access and a custom kernel, but I prefer the nexus factory images, and the only system change I want is an extended power menu. Have you ever actually looked for an odexed version of an extended power menu flashable zip??? Don't waste your time. The last one I saw myself was for Nexus S. It can be done, but it never IS done. Stuff like that I could almost definitely do myself, but I just don't have the time anymore to sit down and read how to do it, actually do it, test it, etc. I haven't done any android dev at all in a few years and I'm rusty as hell, not to mention how much things have changed for android in the last two years.

Speed tweaks for unrooted Verizon version.

Hello there, I figured since we can't unlock the boot loader we need to take every advantage we can for speed. First, even though it's a low resource launcher, I replaced it was apus and have had great results on open ram.
2. There are many services you can disable from Motorola and Verizon without negative effects. This can be done through the running processes menu in apps,I recommend disabling first then uninstalling if possible. I wish I had a list of the ones I disabled but I wasn't taking notes at the time.
3. If the moto notification tool is still running after installing apus them disable it in settings, even with the Google launcher I recommend doing this.
4. Enable developer options, and move the animations to .5 or off.
5. Reboot to recycle your ram and see how your experience is. Hope this helps someone, I am much happier with the performance now.

These are my disabled services, + Verizon navigator

Is there any way to improve ram management on miui v7?

So yeah, I've been using nexus 5 prior I got this phone. It had 2 gigs of ram too. When I was getting RN2 I thought I won't face any ram related problems, but I was wrong. It feels like I have 1 gig of ram judging on phone's ability to keep apps in memory. Chrome is capable of keeping only 1 tab in memory, and not for a long time. I'm sick of seeing everything being reloaded every time I go back to it. Any thoughts on this?
PS
No need to tell me about 'lock' feature in recents, it's just useless.

I set up my own battery profile using the security app. Security - Battery - Battery Profiles. In here I changed the Clean Memory to never.

I use the default profile, and it already has 'never' option picked. And as far as I can judge, this features is meant to be an automatic task killer sorta. The device's problem is in poor ram management, 2 gigs of ram is simply not enough for it, which is kinda 'wtf', considering my nexus experience.

Try freeze build in apps, root first, then use titanium backup or link2sd

If you're using MIUI, there's nothing you can do to lower RAM used by the system and get more RAM available for your apps. I personally clear my apps before use, but the apps I got start fast and are mainly utilities. The only app I lock is School Assistant because it warns me of my classes and exams at University.

Hi.
Im on Xiaomi.eu 5.10.16 with Google Now launcher. No problem having a lot of tabs open in Chrome.
Its smooth and stable. No ram issues. No better or worse than my Nexus 5.
My experience is that using task killers etc only making things worse. We better leave ram management to the os alone
Thanks
Knievel.

Well, I don't use any task killer or something. I just experience ram shortage symptoms.

Kinda late, but eh...
It's not really RAM shortage, but MIUI's asinine memory "optimization". It basically kicks any apps (even active ones!) from RAM after a while. I've been foaming at the mouth blaming my media player for simply disappearing mid-song randomly without any error messages, when I stumbled over the "memory optimization" setting in developer options. Looking around on the net brought me here. Disabled that sucker, rebooted, no disappearing apps anymore. The phone feels as smooth as it did before, so the usual low memory killer settings work. Tweaked them a bit using kernel adiutor and I'm more than happy. You could also try this in addition, but I wasn't able to get it to run smoothly - apparently an exception. Idle RAM usage fell significantly, though.

You're talking about 1 or 2 ?

One, memory optimization. Disabling two, MIUI optimization, is a bit overkill, since it also removes the recent tasks management.

Disable "Turn on MIUI optimization" in the developer options (if you have enabled developer options). After this, you will have to close down recent apps manually (I use "RecentTask" from the Play Store).

In any case, to get rid off the symptoms @sxeMonster was having, it's enough to disable "Memory optimization" in the developer options.

I can confirm the clean memory setting is a major reason for poor battery life,
I've set it to never and my battery life is much better.

That's correct, no need to disable MIUI optimisation.
Memory optimisation option is basically Zram,
I've got it disabled, too.
Haven't had any ram issues and it can still keep a dozen or so apps on the background before android starts killing them.

Non sequitur. MIUI optimizations are not the only (or even the main) difference between MIUI ROMS and AOSP/CM ROMs.

Sequitur or non sequitur, you haven't answered my question - why would I want to disable MIUI optimization instead of only memory optimization?

Your question was "But why would you want to use them instead of the built-in one?" The answer is "This is a very small price to pay for removing MIUI optimization". Disabling memory optimisation may do the deal for you - but it did not solve all my problems.

I will refer you to the following which is in response to issues that have been raised here.
http://forum.xda-developers.com/redmi-note-2/development/b-skinny-pro-t3347906/page9#post66369078

I disabled a few things given by @jajk , I think the most important one for multi tasking is the battery saver, it closes apps and restricts backgroud activity.
Not only that but too much crap is held in memory by miui.
Get disable service and disable:
InCallUI - CallRecordingRemoteService
Security - SecurityCenterAnalyticsService + SecurityCenterService + PowerSaveService --- it still works just not held in memory
Settings - MiuiWifiService + ObserverService ---- Wifi still works
GooglePlayServices - I disabled a few things I don't need and everything works for me except Gmail account sms verification, I had to put in the code manually.
Default SMS app stays in memory for some reason, I disabled it and using google messenger, just gotta disable wearable service
If disabled it breaks SMS, just disable SmsReportService, SMS works that way. Also in settings disable auto download MMS.
I'm getting 600-700 free ram and apps stay in cache much longer. Outside of settings it reaches 800 Free memory + all apps still in cache
Screenshots: https://www.dropbox.com/sh/a7lq8k5jzo2htcc/AAByd8UBFR4AKAiS9Rcg-dWTa?dl=0

I would prefer better memory management than High Free Memory, because Linux is good already with Memory Management.
