Performance

Benchmarks should never be taken at face value. The following are taken from the web-frameworks application, which simply returns an "" with a 200 OK response. These benchmarks compare Frank, Falco, Giraffe, Suave, and WebSharper under a load of 2000 and 10000 concurrent requests for a duration of 10 seconds using bombardier. Frank, Falco, and Giraffe are all pretty well aligned, with each edging out the others in different runs. WebSharper is quite close behind and had surprising bursts of Max values on each run.
