Be careful when using NFSoUDP on recent networking hardware. It's simply too
fast for the primitive reassembly algorithm in UDP. You will get silent data
corruption.

SuSE warns about this fact quite some years in their nfs manpage. You'll
find a lot of copies when Googleing the title "Using NFS over UDP on
high-speed links such as Gigabit can cause silent data corruption."
