Performance Testing -WAS

Hi

I am trying to test an ASP .NET application using Microsoft test tool WAS.

There is an option called client as part of the WAS tool. The documentation says that I need to give the ip address of the client machines from which the testing will be done..

Cant I just use one client machine and test my application and simulate cuoncurrent users for a single machine itself?

Thanks
KalpaFor realistic performance testing, it's also recommended that you run the stress testing tool from a separate machine other than the Web server. The actual request generator can be fairly resource intensive while generating the Web requests and this overhead can affect performance of the Web site under max loads. However, even though the documentation states two machines are a requirement you can certainly run WAS on the same machine as the Web server, but don't expect 100% accurate results especially when you're testing at the top end load for the hardware you're running on.
