The title says it all. I'm looking for a good set of tools that I can use to load test a web application on IIS 7 before deployment.
There are a couple of good tools available:
Not free, but excellent if you are doing this professionally is Visual Studio Team System Test Load Agent. MSDN covers how to set it up and run it here: Controllers, Agents, and Rigs. You can download a trial here:
As far as free tools...
Overview: Web Capacity Analysis Tool (WCAT) is a lightweight HTTP load generation tool primarily designed to measure the performance of a web server within a controlled environment. WCAT can simulate thousands of concurrent users making requests to a single web site or multiple web sites. The WCAT engine uses a simple script to define the set of HTTP requests to be played back to the web server. Extensibility is provided through plug-in DLLs and a standard, simple API.
I believe Apache Bench is pretty widely used for this sort of thing and can be used without any problem against other webservers. It's command-line based, so it should be pretty easy to script into your test suite or pre-deployment scripts.
I have used Web Application Stress Tool before. I'm wondering if this is a pretty standard tool to use, and if there are better alternatives
(WAS) can be downloaded here
There's also a kb article on how to install and use the application here
and a blog on how to use it here
