More performance numbers on JRuby 1.1

I finally got the time to take a deeper look at JRuby 1.1 (trunk).
just checked it out, and ran a small performance test.

Immediately after I ran the exact same test for MRI.

These are the results, showing an approximate 4-10 times performance from JRuby over MRI!!!
