Thanks for the heads-up Jason. ab doesn't have a SD on the req/sec AFAIK, tried doing (I think) equivalent benchmarks with httperf, this time from the server, and I got the following results. It seems like FastCGI is marginally faster than Mongrel for my site when both are run with 2 dispatchers. Does this sound like an accurate test, or did I miss something essential in the benchmarking process?
