.net - WCF Load/Performance testing -

I am interested in simulating many customers who are trying to start multiple WCF services at the same time, Response time Load / stress testing for each customer is available for any WCF services, with many end points (WSHTP, Net TCP etc.). I have heard that SOAPUI is the most popular test tool available, but I'm not sure that SOAPUI can only use the service as a Classic ASMX service (basicHttpBinding because access to WCF services is so much accessible).

Although not directly relevant, the service is using the unit framework behind the scenario to insert something on small object graphs (5-10 entities) and I think that saving calls Not as in the form of fasting, I want to do this in my scenario, in the large number of clients in the form of very small data sets (an array of 50-10 IIS) set in the form of an input.
