[Mongrel] FastCGI performing better than Mongrel - what am I doing wrong?

[Nathan Vack]

Are you running these tests cold? You probably want to throw out the  
first bunch of requests (say, 1000) to better simulate real-world  
running conditions.

Also, what's up with the non-2xx responses? Are you benchmarking an  
error page or something?
