You could try to use JRuby or switch to Ruby 1.9.
Both of them should result in massive performance boosts.
The problem with JRuby is that gems that use C won't compile/work. There are Java equivalents which are installed by jruby's "gem" app, but some of the gems simply don't work
You basically will have the same problem with Ruby 1.9. A little bit of syntax changed, but the main problem is that a hugh amount of gems don't work anymore. People are in the progress of updating though (check progress at http://isitruby19.com/)
