I can copy a 5GB video in about 3 minutes with my gigabit
( with jumbo frames ) network setup.  Even on a 100mbit
link, 11 minutes seems a bit slow.

I'm using:
rw,noatime,hard,intr,nfsvers=3,tcp,nolock,rsize=32768,wsize=32768
for my nfs mount options.

I use autofs to mount my drives via NFS off of my NAS box.
