For improving performance of NFS servers I've often had good success with increasing the 'rsize' and 'wsize' options. The default values are 4096, I personally set them to 16384 which usually helps NFS performance quite a bit. At least that's my experience. Simply add rsize=16384,wsize=16384 to the nfs mount options in /etc/fstab and see if that improves performance for you (values like 8192 and 32768 may also be worth testing, but personally I've found - at least with my setups - that 16384 seems to be the magic value). ('man 8 mount' and 'man 5 exports' also have more interresting options you may want to experiment with, but just rsize & wsize on their own should be a boost)
