Qualcomm-optimized Dalvik. Maybe better than ART - Verizon Samsung Galaxy S 4

So as a Nexus 7 2013 owner, i stumbled upon a thread linked to another thread with optimized dalvik files for qualcomm chips in the Nexus 4 and moto x. People found it to work in the Nexus 7 since it has a pretty similar chip. I then ventured and decided to try it on the S4 since its chip is also pretty similar to that of the Nexus 7. After flashing, it runs just as well as ART, maybe better. According to quadrant (I'm not a big benchmark person, but it does help from time to time), the increase was pretty big. Screenshots of that will be below. Another awesome thing is that since it's dalvik, apps that were broken with ART should work. I tested this with Tasker, but your results COULD differ, but I'm betting they will all work. So you can now get the performance of ART (or better) with all of the app compatibility we all need. These flashable zips only work on 4.4 so don't go flashing them on an earlier version. There is a Q & A section in the main thread where most questions should be able to be answered.

A HEADS UP ON THE BENCHMARKS​
So i just remembered the benchmarks ran were done with my max CPU clock down to 1566 on KT kernel. So with that in mind, running with 1566 max and getting this high of an improvement? That's pretty insane.

For those who would like to see a bench of stock clock before making the jump, here you go

So these are confirmed working on the S4? I remember trying to flash the optimized dalvik about a week ago and the phone would not boot up. But I also flashed the N4 dalvik version lol.

I confirmed it for me after I made a back up haha. Everything runs just fine and didn't have bootloops. Grab the two files from the first post on that thread I linked and you should be fine, but always backup just in case

Just tested this and it deff brought my quadrant score up by about 3,000. I'm gonna test it for the day and let you know what I think, so far I'm impressed. Thanks for this!

Ah, how I wish I was on a 4.4 ROM with my S4 instead of stock MJ7. I did this with my N7-Flo and it worked great.

noticeable improvement on s4 running gummy

Confirmed working on kitkang by euroskank with the CM stock kernel.

Did everyone flash both patches, bionic and dalvik?

People are really over playing ART barely anything is programmed for it.

Well considering I went 1 day 14 hours, almost 4 hours screen time, and 14% left on the stock battery, it worked out pretty well for me.

The method of building runtime wouldn't really affect battery.

The point of it is that all the apps code is already in machine language so the phone isn't constantly converting byte code each time you open an app or do any action with it. That does improve battery life.

I thought that had to be programmed on a per app basis?

I don't believe so. If that were the case, it wouldn't be practical for every app in existence to have to be re-coded to work with art.

It doesn't , I just looked it up. You should read the android police article about ART though. They said right now it probably has more overhead than Dalvik because Google included a bunch of logging data to check stability rather than extensive optimizations.
