RubyConf 2008: JRuby: What, Why, How...Try It Now

Why JRuby? Well the JVM is awesome. 15 quadriliion man years of work or something. 15 quadriliion Sun man years can't be wrong, right?

They have declared that Ruby 1.8 is "done" (again) and 1.9 mode can be triggered with a flag. Full 1.9 compatibility is coming.

Was it two years ago when I first saw them talk? Yeah, I think it was at the Rails Conf 2007. So about 1.5 years ago. JRuby was pretty impressive then and it has come a long way since.

Now that Rails 2.2 is thread safe you can really take advantage of that with JRuby. They showed a ridiculous graph comparing Rails 2.2 under load with MRI and JRuby. JRuby crushed the competition like a grape. (by Jake Scruggs)
