"We now have Qualcomm-optimized Dalvik libraries thanks to recent Moto X 4.4 release."
I found this in the Nexus 4 forums. It improves benchmarks and in most cases makes the phone seem smoother. Enjoy.
I've compiled libraries from several devices and linked them in post #3.

Flash in recovery. Completely undo-able, no partition wipe occurs when flashing.

What does this do?: http://forum.xda-developers.com/showthread.php?p=47913987

Which Dalvik works on which ROM and why

Regarding CM11 Themes and Paranoid Android


TO UNDO:

- Flash the stock file for your device located at the bottom of 2nd post. Choose your build number.
or
- Reflash system partition.


Don't forget to hit thanks! :) I am not responsible for any damage to your device, you know the drill.

Please do not post benchmarks. It clusters the thread and does not reflect real world user experience.
Take your benchmarks here:

Does this actually help performance or just boost quadrant scores?

Sent from my Nexus 5 using Tapatalk


It actually helps with performance with no extra battery drain seen. I have ran this for a week so far and its running like a champ. I can say from personal experience before the patch I would run Maps, BT, Soundcloud, using Hangouts at the same time and would have slight lag when going through notifications. Now grant it was not that bad but more of a personal annoyance in general. Since the patch flash I have not had one single "lag" moment and I can run what I need with no ill effect. Just nan and flash and I promise you will not regret it.

I'm using this since yesterday on Cataclysm + Stock kernel and I got to say it feels really fast. No issues so far. Also it scores pretty high on benchmarks :D

    Extracted the libs from the Korean LG G3 system dump (build KVT49L.F400L10a)

    I don't know what ROMs the Dalvik libs would boot on, nor do I know if they are any better. Flash at your own risk. MAKE A NANDROID BACKUP.

    Dalvik doesn't boot on stock ROM nor any AOSP or CAF ROM that I've tried (Carbon, various Rastakat builds, Purity, CM)

    Bionic works fine as usual and slightly better than the one from the Xperia Z2.

    Extracted from Xperia Z3 (23.0.A.2.93).

    MAKE A NANDROID BACKUP.

    Works fine on AOSP ROMs. I omitted /system/bin/installd since it hardly affects performance (if even at all) and people do not know how to search/read when they have CM11 Theme issues or attempt to flash on PA/derivatives.

    Bionic boots up fine just like always.

    I assume these are similar to the Z2 as Sony releases a new reiteration every 6 months or so. Theoretically they could possibly be better, but they're definitely going to be similar.

    Which Dalvik works on which ROM and why

    Probably what I'm curious about. Wether any of these are kernel or rom specific?
    Kernel is unrelated.

    Certain ROMs have certain commits which stop some Dalvik libs from booting. E.g. "speed up boot on multicore devices" commit stops some AOSP Dalvik from working (usually only full/partial CAF ROMs have this anyways).

    Any Dalvik derived from a CAF based ROM (OnePlus One, CM) will only work on a CAF ROM (regardless if full CAF or hybrid AOSP+CAF), such as Mahdi (partial), CM (full)

    Any Dalvik that comes from an AOSP base (such as Z2, M8, MotoX, and regardless of any OEM skins) will work on any AOSP/stock based ROM such as stock ROM, Rastakat, ParanoidAndroid, Cataclysm, etc

    LG G3 Dalvik is weird and doesn't boot on anything we know of so far.

    Bionic should work on any ROM regardless and there hasn't been a single incompatibility with them as far as we know (only on KK, may have issues with "L", I don't care for it at this point and neither should you)

    Of course, it's more complicated than this, but this is the general, simplified trend, and it seems to have been consistent so far.

    Edit: Regarding CM11 Themes and Paranoid Android

    Edit2: Carbon moved to a 100% CAF/CM base rather than being hybrid AOSP+CAF, so I had to modify my example. Doesn't change what works on it since they were already using CM11's Dalvik anyways.
