    Given the topology of your network, I'd at least try to make sure
that you're using NFS version 3 and TCP as the protocol.  If you're
using UDP, the various rate-changes are likely killing you on NFS

    Definitely try testing the thing using a hub -- and for the best
results, make sure everybody's talking at the same speed.
