I'm sure that Tom Pabst is making a fortune off of it. I don't know if he has a Hebrew mirror. Anyway, depending on how a program uses memory, it can prefer a bigger L2 cache over a faster one. There's a big penalty when your program misses cache and has to go to main memory. In some cases, the extra speed of the Tbird's cache isn't enough to compensate for the extra penalties. -Tom
