Does anyone have any experience tuning NFS mounts on FreeBSD machines?

Not sure if you have tried this but the first thing that I try when dealing with NFS is using tcp mounts rather than udp. Most of the black magic of NFS tuning seems to center around compensating for lost udp fragments on the network. I discovered TCP mounts when I was attempting to update a box laptop to the latest FreeBSD -STABLE. The laptop had no built in ethernet so I was stuck using an NE2000 clone. I didn't realize that under heavy use it would lose packets. This would lead the build process to stall in the middle. Changing from UDP to TCP makes it the kernel's responsibility to track down lost fragments and the kernel does a much better job of it.
