NFS (TCP) Performance

[Peter Galbavy <Peter.Galbavy@knowledge.com>]

Has anyone spent much time with NFS-over-TCP ?

Recent empirical trials on my machines suggest that untarring a
largeish archive like gated (see recent update mail to ports@openbsd.org
:) is "unreliable". Resorting to UDP and all is well, ignoring the
performance aspects associated with NFS in general.

What is really odd is that if the un-tar fails, it fails "hard" in
that it will never return - without a reboot. I would like the option to
use TCP mounts on the (it appears) poor assumtion that TCP traffic
on my network is more controlled than UDP.

BTW Before I dive in there, anyone got a version of tcpdump that will
look at NFS-in-TCP packets - the stock one only dissects UDP RPC ones.
