When CPU Affinity Helps and When HyperThreading Hurts

I'm not a great writer, and have to dedicate most of my time to coding. However, sometimes I do feel compelled to record certain knowledge -- just in case someone else needs it. I've done this many times in lengthy R&D projects (e.g. my WRT54G work), but now I'm taking a different approach - short articles simply stating some fact. I'm calling it the Bitsum Knowledge Base, after Microsoft's Knowledge Base, lol.

Here's a couple short articles I'm working on. Proof-reading and extensions will come in time:

When CPU Affinity Helps
When HyperThreading Hurts

I've got about 100 more I could write, but will start small ;). Maybe these articles will help someone in need, and perhaps gain me a customer if I'm lucky. Many engineers don't take the time to publicly disclose knowledge, which is understandable, but I feel like a more educated population is a better population. Naturally, any writings I do are probably oriented towards the techie type. However, if there is jargon you don't know -- just look it up and you'll understand.
