PFOX lets you assign a maximum number of workers.

Our use of PFox allows a user to enter a complex item, and then immediately enter another while the processing of the first one occurs on another core (we only use it on desktops, not citrix or ts/rd). If you watch VFP in the original scenario, you see one core very busy. In this core, you see 2 or more cores very busy.

Our power users are very happy.

>There are WinAPI calls available to declare which/how many cores a process is allowed to run on. But general reccommenedation is to leave own fingers from such things as often the OS performing its job gets better results as handcra/ufted code, unless the machines the code is running on is totally identical.

I am not sure how you implement multithreading in Visual FoxPro, though, since it doesn't have any built-in multithreading capability. At least, none that is exposed to the programmer.

>>>You are right about VFP being single threaded. But with the help of the VFP community, there are examples of implimenting multi-threading (mtmyvfp by Calvin Hsia) and Parallel Processing (ParallelFox by Joel Leach (?)). I have been adding these features to my FUnit project. I am not sure if the threads are running in on the same core that the parallel processing is running, or spread out to other cores. This would alter the length the of time the test cases take to run.
