Good things sometimes happen to the open source community. Since Facebook acquisition of FriendFeed, a bunch of technologies were released to the wild, including, most notably, a Tornado web server written in Python. The Tornado is touted as a «a scalable, non-blocking web server and web framework». See Wikipedia article
http://en.wikipedia.org/wiki/Tornado_HTTP_Server on some details on the performance of that server, as well as some comparison with other web servers.
Here's the chart, taken from Wikipedia:

The numbers looked interesting, so I decided to benchmark Tornado myself to check out how it fares against some Erlang tools.
