Did you do these benchmarks using NT or Win2K or what ?
You can expect a benchmark from me in the next few weeks using Traffic Jamme, that should do some real testing. BTW, I think benchmarks are more realistic for big websites if done in SMP boxes.
On the documentation, you're welcome. I am glad people are liking it. You can help us keep it up-to-date by submitting bugs and feature requests at the SDM.
