NopCommerce Performance Test Tool

Hi All,
for a big project that starts soon, I need to do a performance test with follow characteristics:

- 700 contemporary users
- each user have to simulate follow actions: login - search product - add to cart - confirm cart
- each script must be running for an hour

How can i achieve this? Is there a tool like Jmeter or similar for IIS?
Thanks in advance.

You can just use jMeter. Its developed on Java but can be used for load testing any web application irrespective of underlying technology. We make use of jMeter for creating load on nopCommerce site we optimize for performance. However for measuring application performance in detail you would need to use a application profiler that profile application developed for dot net.
