I recently wired my house for Cat6 and gigabit ethernet and learned
that this is a very tricky business. A lot of things can go wrong,
such as cables can have too sharp bends, not crimped properly, the
list goes on, and on, and on.

Also, NFS had performance problems when run over gigabit ethernet, not
giving me gigabit throughput. I just did a test. I can transfer files
with HTTP at the speed of 50 megaBYTES per second, but I can transfer
files via NFS at only 5 megabytes per second.

What buffer sizes do you have on your NFS?
I'm not running jumbo frames since I have 100mbps devices on the same network,
and I get 70MB/s on my gigabit connection from my linux client to my solaris
server.

I use wsize/rsize=32K for NFS. I also noticed differences between the two
gigabit interfaces on my asus motherboard used for linux. The Marvell 88E8001
gigabit I/F does much better than the Nvidia CK804.
