1.8.6 is pretty slow, compared to other impls. Ruby 1.9 and JRuby will
perform better, as shown by a few folks. JRuby on a Java 6 JVM with
--fast and --server should perform very well.

I'm also pretty confident that I can get JRuby within a few times Java
performance for non-numeric CPU-intensive tasks. Just not sure when it
will be a priority to make it happen.
