That's not how you should simulate a load on a Web server.  You are limited
by your clients' abilities. In addition there are real limitations imposed my a
DLL (I believe it's called wininet.dll) on the client boxes.  You should be
looking at tools like WebLoad (which I like), WCAT or HOMER and spread
your load across many more client boxes and hand each of them a random
set of requests to hit the servers with.  WebLoad does an excellent job of
this, but it's a commercial product and not cheap. On the other hand it can
do lots of interesting things including merging response statistics with the
performance monitor data.
