A couple questions:

1. What OSs are running on the client and server?
2. What's the output of "rpcinfo -p <servername>"?

Is this over UDP NFS? If so, what's the underlying network architecture 
(Ethernet, FDDI, etc.)? Specifically, what's the MTU? What kind of 
bridges/routers/switches are between the client and server? You might 
try fiddling with the read and write packet sizes ("-r" and "-w" options 
in mount_nfs) to see if you can find an optimal value.
