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% .
