Performance and Memory Improvements in Android Run Time (ART) (Google I/O '17)

This talk presents recent improvements to the Android Runtime (ART). Topics include the new concurrent copying garbage collector (GC) based on read barriers, and improvements to the ahead-of-time (AOT) and just-in-time (JIT) compiler. The new GC reduces pause times and heap sizes compared to its predecessor. Improvements to the compiler include Class Hierarchy Analysis (CHA) to reduce the overhead of virtual calls, new induction variable analysis and loop optimization, a vectorizer to take advantage of SIMD instructions, and a diverse set of optimizations specifically targeted at improving Android application performance. The impact of each optimization is demonstrated with real-life benchmark and application performance improvements.
