My writing isn't the best, and I'm often too busy to elaborate as much as I want, but I figured I'd start posting some useful information about how CPU scheduling works, and how you can optimize your particular software environment.

This article is about how, for single thread (or limited thread) processes, in some scenarios you can boost performance of that process by limiting it to a subset of CPUs. I will continue to write on the article as time passes.

I also posted another about HyperThreading and how it may hurt performance in some cases since your OS can't differentiate between physical and virtual cores. This single sentence sums that up, so I'll not waste time to a link to that short article ;)
