They are the total test run times and I really feel that harmony launches slower than RI. It is the most abvious difference not only from the above result. I have once tested the performance about net and the result ensures me that harmony performances almost as good as RI although the test I run cannot be said a formal performance test.:)

I wonder how different these numbers are for release vs debug builds - guess Leo used debug versions. And surely there are some tricks RI does to achieve this momentary startup - as ClassDataSharing or resident-in-memory VM core after very first start.
