Ruby Virtual Machine Benchmarks?

I’m collecting benchmarks of Ruby on various virtual machines. So far, I
have my own Matrix benchmark on “stock Ruby 1.85” and a recent YARV. I
made an attempt to run it with JRuby last night but I don’t think I had
everything configured correctly – it couldn’t find “mathn”. Does anyone
have any benchmarks that can be run on JRuby and Cardinal?

Yes, I’m looking for micro-benchmarks. :slight_smile:
