btw, it's possible to run Tornado on $NUM_CPU forked processes, have them listen to one port and so you wouldn't need nginx load balancing. Just read httpserver.py and you'll find a fork() there. The downside? Assuming you're still running your Tornado in your console and haven't daemonized it somehow - you press Ctrl-C, it exits (the console part, I mean) - and the $NUM_CPU children are still running. It's still not fixed today, and that doesn't really speak of quality.
