We'd like to see the output of /proc/mounts to help you with the problem. "The defaults" is not good enough because they are negotiated. When you don't specify mount options, they're not necessarily going to be the most optimal. It depends on the kernel versions on both client and server. Most newer clients (depending on the server) will default to TCP, 64K rsize and wsize.
N7700:/raid0/data/backups /backups nfs rw,vers=3,rsize=32768,wsize=32768,hard,proto=udp,timeo=11,retrans=2,sec=sys,addr=N7700 0 0
As I mentioned to James Pearson (but might not've cc'd the list), I am beginning to think this may not be an NFS issue at all, but rather an i/o problem with RHEL's LVM.
