Sure it’s a noop test and running on a iMac i7, but 80K requests per second is pretty impressive for 40 lines of code.

Here’s the apache benchmark information.

I’ve also been playing around with Mizuno and jruby-rack quite a bit recently. We’re hoping to find a high-performing solution for jruby.
