The number of mbuf clusters probably isn't going to affect this at all, unless you're dumping a lot of traffic over the NIC and increasing the number of mbufs allows you to dump more packets. So I'd say replace your fiber. Ken -- Kenneth Merry [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-net" in the body of the message
