QTAGENT.EXE Uses All Available CPUs

I am pretty new to load testing using VS, but I think I installed everything fine and I had a problem when the execution of my load test quickly accumulates to 100% of the processor load. It seems likely that this will affect my test results, and I assume that this is not the expected behavior.

My hardware platform is a wise machine for developers: a few months ago with a quad-core processor, 12 gigabyte RAM, two IDE drives and a fast network adapter. I can clarify if necessary, but usually I would say that it screams.

I am testing an MVC2 / 3 application that runs locally on Win7 x64, against MSSQL 2008, using VS2010 SP1, C # /. NET 4.

The test is based on Unit Test, which uses one MVC controller method, which uses Unity and other Ent-Lib libraries to retrieve a collection of clients from the database according to user rights. Typical runtimes for Unit Test are between 0.4 and 0.6 seconds.

A load test is installed to identify performance problems and runs for 10 minutes:

  • Original user count: 1
  • Step Duration: 30
  • Step Number of users: 1
