Your running with a JIT in winblows aren't you (if you don't know, then
yes, you are; and in vcafe it's one of the fastest in the industry) but
not in Linux (if you don't know then you _ARE_NOT_). Disable it in winblows
and I'll bet you see the performance equal out on that tight loop. Compile
with jikes and I'll bet you see a slim improvement as well. If you're running
serious multi- threaded stuff you might find that linux and native therads
will edge out winblows due to the overall inferiority of the Redmond OS.

Find a jit for linux that you like, use it, contribute to it and/or it's
developers. There are a couple different jit projects out there.
