Just as an onlooker:

I have a new mailserver with a 500 PIII Xeon and a gig Hawkings adapter
plugged into a Netgear 752 stackable with a couple of gig ports. The other
gig port goes to my dell poweredge 1500.

Using a small file (dripping sarcasm) like Server 2003 SP1 (200+megs) I get
a sustained throughput in the 120mb/second; 12% saturation. I'm guessing
i'm coming up on the Xeon's ability to make the push as it's almost pegged
on taskmanager (about 98%)
