I tested it on my genetic algorithms library. Lots of metaprogramming going on in the initialization, and a lot of calculations afterwards using the generated modules and classes. First tried my tests. Finished in 34.726 seconds. 33 tests, 626 assertions, 0 failures, 0 errors That's better than 1.9, which couldn't handle some of the metaprogramming. Then tried a benchmark: 1.8 : 676.75 seconds (ubuntu/apt-get) 1.9 : 161.99 seconds (svn/-O3/no enable-pthread) JRuby: 302.23 seconds (java opts -server, jruby +C) Did JRuby just outperform 1.8 by a factor >2 ? I'm impressed. Great job JRuby team.
