It mentions Grizzly on Rails (see the "Ruby and jRuby, Mogrel, Goldspike, Grizzly and GlassFish" earlier post), GlassFish v3 and some interesting benchmark numbers against Mongrel, GoldSpike and WEBrick. With the appropriate underlying technology, JRuby on Rails seems to be ready for the enterprise performance-wise. Service providers would be a good judge too.
