Very nice benchmark. As developer of a toy "framework", but powerful http server library, I wanted to check on my project. I did a fast blog entry at http://bit.ly/10l9Smj. I got ~58288.10 for simple json, 8594.39 on db using sqlite, 503.23 for 20 requests.

Anyway for me its more important speed of development than performance on the server. Maybe my servers do not get that many visits.
