I have a very different experience with NFS: we are using Gigabit Ethernet, and a 64bit RHEL6 clone with ECC memory as a file server; it has RAID1 ext4 home directories and RAID6 ext4 for synchrotron data. We have had zero performance or reliability problems with this in a computer lab with ~ 10 workstations, and I have seen 115 MB/sec file transfers via NFS, at peak times. Just make sure to export using the "async" option.
