Tooting my own metaphorical horn a bit, but it was relatively easy to put together a Jetty-Rack interface for high-performance webapps. It's called Mizuno, and lives at http://github.com/matadon/mizuno http://github.com/matadon/mizuno Internally it uses Jetty's event-driven I/O, so performance is on a par with Thin and Passenger, at least on my MacBook. I'm a bit pressed for time at the moment, so if anybody wants to add in the cometd servlet (it's in the repos) and write a tutorial, that'd be awesome, and if not, I'll get to it in a few weeks.
