I was wondering if there are any Nexus 4 ROMs using JustArchi's optimizations (link). I did my best to compile OmniROM with these fixes, but I am not very experienced with Android development.

Looks like our devices are too fast to use these "insignificant" compiler optimizations

I'll give my 5 cents these days to try compiling it..

+1 for this thread.. I asked just the same thing in the general Q&A thread and nobody answered.. I'd like to see CM, ParanoidAndroid...etc.. built with ArchiDroids optimizations..

Wink Like to see that too!
I've been searching for a rom with f2fs support + JustArchi's optimizations. Can be possible?

Nevertheless, there are other statements that say it is faster, we can only know for sure if we benchmark this and find someone willing to compile a rom. Perhaps @legolas93 is willing to be so kind?

yeah i saw those,luck for them, thats why best rom threads are not allowed on xda, people get different results on their devices :P,i plan to compile aosp with those just to test on the n4, but i doubt i will :/

No one is going to try this anytime soon.
The code is no where near perfect and it sets up an environment where there is a lot of room for errors which will result in VERY bugy, glitchy, crashing Roms.

The code is really sloppy and so far only JustArchi is the only one that has successfully used this in a ROM with out error.

There is still a lot of going back and forth in whether this really works since android isn't 90% thumb

All this is good for is benchmark scores. Just like F2Fs its all placebo in real world performance.

With a quadcore 2 gig phone... You're not missing much.
Legecy devices will benefit in the least from this.

First build is ready!

It is mako-userdebug.
I used Linaro toolchain(JustArchi's link) and JustArchi "JustArchi's ArchiDroid Optimizations V3" -
It is without Gapps (so PA Gapps must be used).

Build Env :
Debian GNU/Linux testing (with make downgraded from 4.xx because AOSP lunch require this).
AOSPA soruces 4.4.2_r1 used for the build.
No ART patches! ART will fail if you try using it.

Will test this today on my phone, and if successfully boot, I'll post a link for the ROM.

p.s : From back these days, where people find that AMD64 arch is here, Linux builds started to optimize the speed of your GNU/Linux for your specific CPU (Gentoo for example, or Debian GNU/Linux moved from i386 to i686 and after that to AMD64). Well, the tests and builds performance charfs finished with this : improvement of the speed was was something like 0.6/0.9% ... So in the real world reality do not expect much from this!

Regards ...


Boot failed
Next time, I'll enable the proprietary drivers in the build.
Currently new build is running with enabled prop drives settings like:
To use these proprietary files, comment out this line in device/lge/mako/
