Firstly, I just want to say that this is not my creation, I take no credit, and I'm posting pretty much what it says on the original thread right here. If you wanna thank the devloper (Androguide.fr), follow the link below. I'm posting here so more i9100 aka Galaxy S2 owners can take a look.
Original thread: http://forum.xda-developers.com/showthread.php?p=32660318
UPDATE!! I'll post update changlogs here, if you dont feel like going to the original thread.
v2.1.2
- Fixed conflicting tweaks that caused bootloops and/or were breaking network on some devices
~ Please report if these kind of issues persist ~
- Made the package lighter by removing some unused left-over files from previous versions
v2.1.1
- Fixed missing chmod script which was preventing init.d scripts from running
- Possible fix for the apps that aren't installed properly on some devices
v2.1
Introducing a new tweaks selection screen : Pimp my Kernel
--> Tweak 6 of the most common CPU Governors : Ondemand//OndemandX//Interactive//SmartassV2//Lulzactive//Conservative
--> Tweak your default I/O Scheduler & Disable I/O Stats
--> Disable & Re-Enable VSync
--> Disable Normalized Sleeper // Gentle Fair Sleepers // New Fair Sleeper (just moved, was already there before)
-->Misc. Kernel Tweaks : Disable kernel error checking (already there before) // Sysctl kernel msgmin & msgmax tweak
Added an option to revert Adblocking
Fixed the issue where beats audio and walkman options would be displayed for gb roms when it shouldn't
Various bugfixes (a few swapped selections and unworking tweaks)
Removed the extra apps screen, this wasn't really matching the mainline of this project, since you can grab those apps from the market. Plus this makes the whole package lighter.
Switched to miui installer theme
v2.0
ø New Tweaks selection screen : Multitasking
==> Choose between :
4 levels of OOM Priorities
4 levels Minfree settings
2 levels of ZRAM compression
Tweak your kernel and dalvik cache to behave well and be stable on hard multitasking conditions
ø New Tweaks selection screen : Networks & Internet
==> Security tweaks :
Reinforce your TCP/IP Stacks to make them resist to SYN attacks which cause a DoS (Denial of Service) on your device. Now those lame-ass blackhat hackers won't harm you with this.
Block redirects : auto website redirections will be blocked
Block source-routing : source-routing can be used to hack into your device as it allows full tracing of packets.
==> Stability & Speed tweaks :
Increase the buffer and queue size of each tcp socket to give more stability on high broadband consumption conditions
Allow the system to re-use the Sockets on TIME-WAIT state. In clear time-wait causes memory-loading, memory-loading causes internet lagg, internet lagg sucks.
Various IPv4 protocol speed tweaking scripts using sysctl
DNS and ppp0 tweaks for faster name-resolution, which means faster connections to websites.
ø New Tweaks selection screen : GPS Configuration
==> Choose between 79 countries (and 5 continents) of gps.conf files: those files are essential for the accuracy and lock-speed of your device's gps. (Thanks to gangsterjoop for the files)
ø New Adblock file of over 200 000 hosts ! (100x more than before) (Thanks to BSDgeek_Jake for the host file) --> added to extra features screen
ø New init.d scripts :
Move Dalvik-cache to /cache to increase data storage
Bind-mount dalvik-cache to allow a device to boot without sdcard (useful for devices with damaged internal sdcard)
Touchscreen responsiveness improvement tweaks
ø New Enable/Disable features :
Disable and Re-Enable Android logger
Disable Gentle Fair Sleepers
Disable New Fair Sleepers
Disable Normalized Sleeper
ø Rewritten every single init.d script :
This allowed me to realize many of them were not working, so I added a lot of missing values, and fixed a countless number of errors, redundant values and typos. So there should be some big improvement on the effects of init.d tweaks.
I also set an order of execution of init.scripts to avoid conflicts.
ø Removed themes and S-Voice
The S-Voice flaw that allowed other devices to use it appears to be patched and it was heavy, and themes were heavy and not really useful, you can download a countless number of them for free on the market
ø Changed installer theme to Sense
I realized that the options subtitles were not readable with ics theme, so most of the tweaks effects explainations were hidden.
ø Pimp My Rom will now come in two versions :
One will include the latest version of Aroma (with touchscreen working out-of-the-box, but issues on some devices) and One using Aroma v2.51 (With touchscreen calibration, and this version appears to fix the weird texture/ghost-input/moving screen/vibration issues people have with some devices with aroma v2.56)
ø Major code clean-up, various bugfixes
Re-organized and cleaned-up both aroma-config and updater-script
Fixed the way the installation process input displays sections and sub-sections
Fixed some tweaks getting installed instead of others when they shouldn't, and some other bugs
Pimp my Rom is an aroma-installer based script that will allow you to choose between a plethora of nice tweaks, mods, apps, themes and features to add to your current rom.
YOU CHOOSE which options and tweaks to apply, all this with a nice touchscreen interface, even if you're not running a touchscreen recovery, thanks to Aroma.
You can now run this script on any Android Device !!! (GB/HC/ICS/JB)
PmR was originally created for the Galaxy tab 7.7 (p68xx), but it has now evolved into a universally usable script !

No the link is fine and thank you all for such a positive reply , I'm sure Androguide would be really happy.

On mcm11's today's sysfs nightly version, it works but with the CM kernel. If you apply dorimanx kernel, it stops working. The device doesn't boot. First boot with the dorimanx kernel and this mod active works but from the second onwards it stops working. Just reporting.
Other than that the mod is great! Loads of tweaks and scripts to choose from currently using it on the cm10 kernel.

Works on paranoid android 2.21 with DorimanX kernel. :victory:
Sent from my S II ( "Jelly Bean'd Monster" )
Installed it on cMIUI 2.10.12 with DorimanX 7.1. The UpdateMe app gave me a FC instantly and won't open, but other than that no problems. It's working as it should be.
Will report after a few days of usage..
EDIT: After a day of usage, no FCs no problems at all. I don't know if it makes anything faster, but there are no problems so I will keep on using it.
Installed on JellyBam, everything seems okay now, will report later for any FC's.
Thanks
Working perfectly on a ported version of AllianceROM for the i777, using DreamKernel 2.7.5.
Thanks for bringing this tweak collection to our attention!

This is awesome, thank you for sharing!
Well I know this is an old post but does this works with CM11?
What sections of kernel code are changed for optimization of performance.
Like we can change
1) the minimum free memory that android need to keep free.
2) Rate of clearing cache
3)Advanced LMK- where we can kill more than one process at at time when memory scarcity occurs.
4) Reducing logging.
5) In framework we can change the oom_adj value of important processes.
6) Implement Zram for kernel.
7) change the minimum and maximum no of process for AMS.
I want to know all the changes that can be made into kernel or framework code to optimize performance.
I also want to know how can we implement swapcache for android kernel. What changes do i need to make in the code.

A owner named Radhe Shyam Dewangan on fb development page says that He has flashed this update in his quattro. I'll post here reviews once he lets me know about it.
Hoping it works. I'll try myself soon as well. :victory:
Cheers ! ! !
Reviews are very positive it seems. He haven't checked the antutu scores. I'll be trying soon with current antutu score and after update antutu score.
Till then Happy flashing...
Testing... The phone is already faster...
Thank you!
I have installed this mod a week ago.. and phone feels more responsive, but I do not know if crossbreeder MOD http://forum.xda-developers.com/showthread.php?p=37062006 and Updated Adreno2xx/3xx GPU libraries helped, but hey!, everything counts (and helps).:good:
I tested it and I'm not sure if it's something I'll keep installed. Before installing, I downloaded Antutu and my benchmark was 11484, after installing this mod, I re-tested and got 11272 (isn't it supposed to be faster?). Also, I noticed that my phone was hotter than usual. Don't rely on placebo effect, use a benchmark instead.

You need to download a file called Adreno_200-AU_LINUX_ANDROID_JB_REL_2.0.3.04.01.02.21.099.zip and flash it via CWM...
I must say you need to backup your system partition If somenting goes wrong...
Do not remember the specific topic form which I downloaded this file (I owned a LG E612.. search for it on that forum)

:good:
up to 10 post hix,up for everyone
Good day , I have a general question about these and hope someone could explain me what exactly happens there:
So , I played around with some props values ( also looked a bit into the aosp code / dev docu ) and set these values with magisk as system.prop
dalvik.vm.isa.arm64.features=Default
dalvik.vm.isa.arm.variant=cortex-a76
dalvik.vm.isa.arm.features=Default
dalvik.vm.heapstartsize=16m
dalvik.vm.heapgrowthlimit=256m
dalvik.vm.heapsize=512m
dalvik.vm.heaptargetutilization=0.5
dalvik.vm.heapminfree=8m
dalvik.vm.heapmaxfree=32m
dalvik.vm.dex2oat64.enabled=True
dalvik.vm.dex2oat-flags=--debuggable
dalvik.vm.dex2oat-filter=everything
dalvik.vm.image-dex2oat-flags=--debuggable
dalvik.vm.image-dex2oat-filter=everything
dalvik.vm.dex2oat-Xms=16m
dalvik.vm.dex2oat-Xmx=512m
persist.dalvik.vm.dex2oat-threads=8
dalvik.vm.dex2oat-threads=8
dalvik.vm.image-dex2oat-threads=8
dalvik.vm.boot-dex2oat-threads=8
dalvik.vm.jitmaxsize=128m
#extrem values ! Default would be 10000
dalvik.vm.jitthreshold=2500
dalvik.vm.jittransitionweight=333
dalvik.vm.jitprithreadweight=333
pm.dexopt.install=speed
pm.dexopt.bg-dexopt=speed
Note here that I used first dalvik.vm.dex2oat-Xmx=256m instead of 512m , after a Dalvik clean up and rebuild I had 248m of Dalvik cache , no noticable performance impacts etc , I though It would be better to raise the value. In the same reboot process to enable the changes I also did an update , now my Dalvik cache is empty and can't be rebuilt , the interesting part is that my system is now quicker ? Especially in games I can notice a significant boost in startup time and menu transitions , but firefox (the only app atm) doesn't like this but can be used normaly after 3 "crashes-to-launcher"
Side Note: I don't need answers how to repair anything , I'm curious what's going on
So my questions is first how can it be faster if it presumably uses the default java JiT in memory instead of creating Dalvik cache + odex files
And what happend that Dalvik etc can't be normaly initiated ? Does it not like the settings and simply crash , or is this the right behavior for my settings and I have simply no idea what I'm doing ?
Thank you for reading and any helpfull response
Both the Dalvik ( uses Just-In-time compiler, JIT ) and the ART ( what uses Ahead-Of-Time compiler, AOT ) are a Android runtime. ART is the default runtime since Android Lollipop. Knowing this you have to clarify what Android OS you are trying to hack.

Right it would probably good to know my setup , I use the Mi 9T with Miui 12.3 on android 11 , ram is 6gb , cpu/gpu is SDM730
Thank you for the first clarification , so does this mean the JiT is on newer OSs ineffektiv ? Or just a backup technique
