Good point. However the numbers Harsh reported for his ParallelFox tests seemed to show high CPU utilization, low RAM use and (perhaps surprisingly) low disk I/O utilization, seems pretty CPU-bound to me. Not sure how much slack there is in the VFP tasks to productively run extra instances.

Harsh has a good environment to run some tests - maybe he can let us know :)
