Here's a data point...

Server has dual Pentium 4 processors @ 2.8 GHz, Windows Server 2003
Client has Core 2 6600 @ 2.4 GHz, Windows Vista & CA eTrust antivirus
Gigabit networking
Repository has 49,000 revisions

A checkout of trunk (900 MB, 28000 files) takes 5'00"
An export of trunk (450 MB, 9000 files) takes 3'20"
An update of trunk (94 files actually updated) took 0'30"

John
