I guess I am overestimating the = horsepower of this machine. Oddly enough, while ntop itself claims to be using 80-95% of the cpu, = the user/system/irq generally does not add up to 100%. In fact, user is = generally 15-20%, system is 20-50%, irq is <10% and idle is >35% all the = time. I set the debug_bpf_bufsize also, to 65536. No change. Sounds like I get to spend some more money :). -Will To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
