[Mono-dev] FastCGI Performance

[Alfred Hall]

I've been experimenting with hello world requests running under self-hosted
Nancy and I'm getting about 2000 requests/second and sometimes locks up
after a long period of time. When running similar test using Golang and
Martini I'm getting around 4700 on the same hardware. I'm concerned why
there is such a big difference between Mono/HttpListener and Go. It
shouldn't be that much slower.

Anyway gonna try your FastCGI implementation with Nginx in front and see
how it performs.

Keep these benchmarks coming, that's the only way Webstuff on Mono will
improve! We need to get Mono higher up in
