I've read that there is a jit compiler module for dalvik vm on the works and the results are quite promising. Some people claim an improvement of 100% in terms of execution speed. Does anyone have an idea when it is going to be incorporated in an android release? The amount of RAM on the nexus one (512MB) hints that a jit may be introduced soon. Android 2.5 maybe?
You are getting it all wrong :) There is a JIT in the work, and it is not RenderScript. RenderScript is something totally different.
