I have to simulate a load of 50 users, to test performance an application. As the need of virtual users is less i decided to fire the load from the controller itself, rather than having a controller-agent set up. But as and when the load is incremented and breaches 30 mark, the Physical Disk - % Idle Time of controller is hitting 35%.
Will this cause a I/O bottlecneck, and the performance test results will be impacted?
The Test controller - Agent setup will be a better approach even if the virtual user load to be genearted is merely 50?

I think this depends on the complexity of your test and the configuration of your test machine. I am not sure if there is a specific number, the max is 250 virtual users but the min could vary. If you reach a point where you are running out of resources, you should consider using a test rig setup.

There's not a specific number bar for Physical Disk %Idle Time counter, but 35% is quite a low number that I think you need apply test rig. 35% doesn't affect the performance test but if you want to increase the load, you'd better apply test rig.
