Load testing WCF service (hosted on IIS)

Question

Hi,

What tools are there that I can test out a WCF service?

I am expecting allot of load so I want to have an idea how much a single server can handle.

Answer 1

Start with this:

http://www.codeplex.com/WCFLoadTest

It doesn't do everything possible with WCF, but it is the best tool to start with. Worse comes to worse, it's not that hard to write manual invocation code with web services. They are much easier to load test than web sites.

Answer 2

WCFLoadTest all the way. I've even talked to MS guys who swear by this tool.

Visual Studio also has some load testing tools available, but I cannot vouch for how well they do their job, nor can I say which versions of VS contain the load testing tools.
