I'm glad you corrected your mistake (re: cache speed). No apology necessary, of course. Anyway, in an earlier post, you stated the following: processor speed PPro/200 1 PII/300 1.41 PII/400 nowhere near 2 Now if you're arguing that Crafty fits in the 512k L2 cache, and you agree that the PII/400 part is 33% faster than the PII/300 part, what's up with your commentary on the PII/400? It seems to me that 1.82 is very near 2. The only way I can think of to explain the table above is that Crafty is dependent on memory. >I didn't find "a xeon". I found a *lab full*.

You're not going to impress me with these statements. -Tom
