It may not be related, directly, but one thing that I noticed,
while trying to sort out my own recently commissioned NFS setup,
is that the -r1024 mount flag is *crucial* when the network is
100BaseT and the server is a new, fast amd64 box, and the client
is an old P3-500 with a RealTek ethernet card.  It works fine,
now, but tcpdump showed that it was retrying forever without.
Even NFS over TCP seemed to suffer a bunch of error-related
retries which amounted to stalls in the client.

Is there any way for this sort of thing to be adjusted
automatically?

Cheers,
