I have an application that tries to open as many http requests as possible (in order to stress test a proxy implementation)

It seems to me that Win7 (SP1) may have a limitation on number of concurrent opened connection (it may be the so called half-open state if I'm not wrong). Is there something I can do for client ? and also I test using a vista PC that acts as a proxy server.

It would be great if I could configure it to sustain at least 50 new connections initiated / second on client side and many more on server.

I made the modification according to this technet article by setting TcpNumConnections = 150 but it doesn't make a difference. I still only see about 20 tcp sockets associated with my http client by using tcpview.
