9. How to decide ideal number of threads ? codeproject.com

There is no easy correct answer to the question. It really depends on if/whether your threads are ever going to be waiting for i/o (disk access, network, etc.) and how long those waits will be versus the cost of switching threads. If your processor core is only ever going to be waiting on data from RAM, then ...

10. In C# can I specify a preferred core number for a thread to be executed? codeproject.com

I'm not downvoting you, but: BeginThreadAffinity/EndThreadAffinity (on regular .Net) usually improves the performance computationally intensive threads - so if the computer is dedicated to the execution of some parallelized heavy calculation, it makes sense to do this. Appearantly that automagic doesn't work as well as one would have liked, because I've experienced more than 20% improvement in execution time, something that ...
