JRuby 1.1 beta 1 released

Last Friday JRuby 1.1 beta 1 was released:
http://docs.codehaus.org/display/JRUBY/2007/11/02/JRuby+1.1b1+Released

The last time I tried to check out from trunk (about a week ago), I couldn't get it to work properly with the Rails support in Netbeans 6.0 beta 2, but I'll try it out again as soon as possible.

The performance is now better than MRI (the original C based Ruby implementation) in 14 out of 18 tests, and what's very important to many: It's even faster on Rails!

JRuby is now the most performant option for Rails deployments. w00t!

Congrats JRuby team! :-)

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!!!
