I contributed the tornado script to this project, but the results of it are yet to be published (or if they have I've missed them). I haven't tested it myself on AWS, just on a physical desktop machine, I got great results, but they are so good it of course seems to be an irrelevant comparison.
I have benchmarked the ws4py code in the test on that machine, and it was much slower than the tornado code - quite obvious since it ran in a single process thus on a single CPU.
BTW The default number of processes when you fork is the number of CPUs, which sounded like a fair estimate to me, not knowing the target machine, so I left it.
