Back in February, I installed a modified Dalvik library that included a JIT onto my trusty T-Mobile G1 (HTC Dream). While any noticeable improvements are likely caused by a placebo effect, the benchmarks do not lie. Even on my G1, the oldest Android device released to the public, the JIT shaved a few seconds off the results of the BenchmarkPI application, ~3 seconds to be exact.
While this may not be overwhelmingly awesome just yet, I can not wait to see how the final JIT (that Google is working on and will release at Google I/O 2010) performs (Myriad is also working on a JIT, so maybe a little JIT showdown will take place sometime in the future?).
Anyways, enjoy these screen grabs of the BenchmarkPI application:
So, want to try out the hack yourself? Head on over to the post on XDA (I recommend using the VMLIBS.zip method, so scroll down until you find it in the first post).
