Alan, is it normal for FTP to be 2x as fast as NFS?
With 100mbps, I never seemed to have any issues, but with GIGABIT I
definitely see all sorts of weird issues.

I wonder how much faster NFS over TCP would be, or if NFS in the kernel is

On Linux NFS over TCP is slower than over UDP ~10%.
For the specific case you measured. Its never quite that simple because
behaviour over different networks and error patterns varies a lot and
TCP can be a big win on loaded networks or under error conditions,
especially packet loss, where fragmentation losses kill throughput on
UDP.
