It does depend a lot on what you're doing. You are probably right if your workload is "make buildworld", but for most multi-media applications L2-cache is not interestingly different from raw DRAM, (because of the data volumes), and the only useful caching performed is that done in function kernels, by the L1-cache. I believe that the Celeron has as much L1-cache as any other processor out there at the moment (more or less). -- Andrew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
