As a scratch SMP box, there's very little that beats a dual P5-90. It also keeps you honest on slowdown problems, which you might not see, if you had 2 processors each going 10-20 times the clock rate in question. I also like it because the IPIs and synchornization are relatively costly, which is a good approximation to a faster machine with many more CPUs. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
