Is there any reason that FreeBSD doesn't have such a state? "iostat" also seems a lot less informative than Sun's. What should I be using to measure I/O utilization on FreeBSD? -- Ben 220 go.ahead.make.my.day ESMTP Postfix To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
