Episode 38. Hyperthreading, L1/L2 caching, cache busting, thread trashing, and priority bumping!

So we hear about HyperThreading and how it is sooo cool, well, it is and it isn't. If you are really trying to squeeze performance out of your application HyperThreading might not be what you're looking for. There are so many other things that happens at the CPU level that have so weird names (like Thread Thrashing, 'say whaaaat?'). If you are really serious on squeezing every worthy CPU cycle of your app (or if you're interesting on what really really goes under the hood) take a listen! (ah! and treat me a beer, if you like what you hear!)
