Is their a program that test's resources?

I'm writing programs for the web and i would like to know if their is a good program out that will test resources used when the program is being run, and if possibly simulating the program with like a few hundred users using it.

Thanks

Keith

Depends on what your programs do but there should be some "stress testers" type out there. The other option is to get beta testers. ;)

there's lot of software that tests "resources".. however your question is about stress testing an application.. And again there are alot of stuff out there.. however you're gonna pay for the good stuff..

i used to work with some of mercury interactives tools..
