I hadn't done any significant benchmarking with these settings as I
switched to iSCSI instead of NFS.  However, these were the settings we
had and what NetApp had suggested to us.  I never noticed any
significant performance issue with them.

On my NetApp:

nfs.tcp.enable = on
nfs.tcp.xfersize = 32768

On my Linux system:

net.core.rmem_default = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
vm.lower_zone_protection = 100

My NFS mount options were:
hard,nointr,proto=tcp,suid,vers=3,rw,bg,rsize=32768,wsize=32768,actimeo=0,timeo=600
