I'm not convinced this is a fair test either, particularly unix vs windows, for 2 main reasons: 1) The Apache port has not recieved as much attention as the unix ports, in terms of development effort/time 2) Implementations of identical features may take radically different code paths, not all of which are equivilant in performance. There may indeed be better ways of implementing feature X on windows than on unix, but because it's a port, those implementations may not have been used. I'm not convinced there is any such thing as a fair benchmark, nor am I convinced that benchmarks are valuable. Clearly the benchmark cited is flawed, but what benchmark is not?
