Updated for current JRuby trunk:

JRuby:

Ruby 1.8.5 patch 3876 on java
It took 7.237 seconds to run. 138178 iterations per second.

If I make it run a bit longer, the disparity is greater:

n = 10_000_000

JRuby:

Ruby 1.8.5 patch 3876 on java
It took 61.918 seconds to run. 161503 iterations per second.

Ruby:

Ruby 1.8.6 patch 0 on i686-darwin8.9.1
It took 107.181442 seconds to run. 93299 iterations per second.
