This is not my work but found it on the Xperia Z forums
I have installed it on my STOCK 4.4.4 (108) ROM and I wouldn't be able to tell the difference, yet
What is the differences of Dalvik, Optimized Dalvik and ART
This optimized dalvik I believe speeds up benchmarks (not that we should care about that) but I want to know the true value and what it truly does
of course, set backs if any
Flash at own risk
