VSTestHost.exe uses only one CPU

I recently noticed that while running a load test, VStestHost.exe uses only one CPU. Trying to change the affinity through task manager has no effect and it continues to run on CPU0. Is that expected behavior or there's something wrong in the way I am executing the load.

Hi Pawan,

This is by design in Visual Studio 2008. To drive additoinal load, and utilize all CPUs, you need the Test Load Agent / Controller to create your test rig.

Thanks George,

so what it indirectly means is that I'll have to procure additional licenses for Load Agent and Controller.
Just wondering if both of em are shipped as part of the MSDN subscription?

Hi Pawan,

Each Load Agent license covers a controller, so the controller is part of the Load Agent purchase. For MSDN, they have a trial version, but be warned its double time bombed - I think its 60-days or 25 test runs, whichever comes first.
