Interface type/speed is less important than number of open sockets. I've got an NFS server with a 100mbit card in it that is pretty heavily used the whole day, and after 22 days of uptime, netstat -m shows: 72/596/2112 mbuf clusters in use (current/peak/max) That's just using whatever value of NMBCLUSTERS a 'maxusers 100' gives me. On the other hand, when the Star Wars trailers were released last year, I was a mirror site, and ran out of mbufs a couple times because I had a lot of backed-up FTP connections over a T1 link. Easiest way to determine what you need is to just let the system run for a while, and then rebuild the kernel with your NMBCLUSTERS set at your peak value + 50% . -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
