This paragraph made me smile: > Since Dalvik only compiled at runtime, the compiled code was never written to disk. [...] This would lead to a lot of disk thrashing [...] Since ART is already compiled, the compiled code can be paged out to disk (emphasis mine) It's funny that we still call disk any slower, non-volatile memory (and it's even funnier to imagine an Android phone with an actual disk).
