How do I do load/stress testing of wcf services hosted in a windows service?

Question

We have around 15 wcf services hosted in windows service. Some of the are in .NET 4.0 and some in .NET 3.5.

I would like to know how to perform load/stress/performance testing of wcf services hosted in windows service. The client uses .net tcp binding to communicate with the services. Also, most of the API's return a stream for performance's sake.

I was able to find some tools for wcf service testing hosted in IIS but dont know a way to do load/stress/performance testing for services hosted in window service.

Any help is appreciated. Thank you.

You should be able test using Visual Studio 2010 Ultimate edition. The basic process is to simulate http requests.

The easiest way I can image would be to create an app to call the web service you want to test in a pattern similar to that way you expect normal applications to call it. Use Fiddler2 to record the https session. Save the session as a visual studio web test. Load the webtest into Visual Studio and convert it to a coded web test. This allows you to control the security etc that is uses against the web service.

Visual Studio 2010 Ultimate edition is required to run the load tests, but webtests are creatable with normal editions. Really hard out testing also requires a licence for the virtual user packs, but the Ultimate edition allows testing up to 250 virtual users with a single CPU. This is enough to get a good idea of the performance profile of the webservice.
