Thanks Adam, Do you need to use a particular version of Jetty to support NIO? I'm hazy on Jetty details, but do I understand correctly that if you use NIO then you won't use Jetty's servlet framework but you'll access Jetty at a lower level?
Good news that you've achieved good scalability. Did you try both ChannelRepresentation and InputRepresentation and if so did you notice a difference?
