Looking at this times, I'd say they are mostly about startup time, not
steady performance per se. 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.
I eager to anticipate Harmony will compete strongly in this field soon enough.
