Looking even at your standard deviations, I don't see much of a difference between these. What's your SD on the req/sec?

I tried benchmarking the same site behind an NGINX proxy with both
fastcgi and mongrel, and for some reason mongrel is performing pretty
poorly in comparison.

Any idea what I might be doing wrong?

Here's my benchmarks for 1 fcgi:
