I'm running some informal tests that will show communication latency of a virtual com port USB device receiving a short message from a Windows host computer. What I want to vary is the loading of the host computer because I'm hypothesizing that the latency will be a function of loading.
I realize that the term "loading" can take many forms and there's probably a variety of different loads one can place on the host computer. I'd like to be able to find a ready made Windows loading test tool that will load my computer in a variety of different ways and be controllable.
Does anyone know of such a tool?
