If you have a program that takes a while to run, I think jruby is worth 
trying.  I often find small benchmarks show ruby 1.9 and jruby fairly 
close, but anything more substantial and I get a consistent 2.5-3 times 
speed up using jruby - these speedups are for fairly intensive AI 
algorithms, like k-means clustering.
