I have not got round to playing with JRuby but if you can squeeze 10-30% extra performance then I am keen!

  I'm a big fan of JRuby for two notable reasons. First, JRuby runs on the JVM, which is arguably the most mature and tested VM on the market today; second, you can leverage both the Ruby and Java ecosystems without any additional overhead (the Java interop is almost seamless). Being able to write classes in Java (or Mirah) where speed is crucial, and use them from within JRuby without having to do any additional work, is a nice bonus as well. The only downside is startup time, but that's been improving a lot recently.

    I believe Rails can also run on the JVM via JRuby. I wonder what the benchmark is between Rails/JVM and Grails 2.0 ???

      Rails runs quite well on JRuby, indeed. I have no information on its performance relative to other frameworks, though.

      Rails 2 and Rails 3 run beautifully on JRuby. Github:FI (the locally-installed version of Github) was, for instance, a JRuby application.
