windows xp. intel core2 1.86GHz

JRUBY:

C:\jruby\jruby-trunk\bin>jruby calculate.rb
55

It took 41.125 seconds to run. 24316 iterations per
second.

Not so good. Let's disable ObjectSpace:
C:\jruby\jruby-trunk\bin>jruby -O calculate.rb
55

It took 11.109 seconds to run. 90017 iterations per
second.

That was good. Now let's give it some more juice:
C:\jruby\jruby-trunk\bin>jruby -J-server -O calculate.rb
55

It took 5.75 seconds to run. 173913 iterations per
second.
