Notice: The results here is not accurate. But, you can get a rough idea how everything works. Refer to this: http://www.brianp.net/2008/10/03/changing-the-length-of-the-time_wait-state-on-mac-os-x/

The recent release of the realtime Tornado frameworb from Facebook(friendfeed) is really cool. But, the real question is: how is the performance of Tornado?

After reading the post from apparatus camparing Twisted with Tornado, I decided to do a performance test on Twisted equivalent in Ruby - EventMachine. I used Thin as the server and Rack middleware to test the speed of EventMachine. And, since there was someone in HackerNews curious about how MochiWeb performance on the test. So, I decided to include MochiWeb in my test.

I ran into problems of 'apr_socket_recv: Connection reset by peer (54)' when I tried to run the test on twisted(cocurrency > 75) and mochiweb(cocurrency > 50).
