Hi folks,

When users are running nautilus on a machine where their directories are
nfs-mounted, nautilus spends a substantial fraction of the client
machine's CPU, ~1.5Mbps of bandwidth, and a large load on the server's
nfsd I/O wait states.  It looks like it is constantly stat'ing all the
files it can, although I haven't confirmed that with strace.

Initially the problem was with the gamin daemon doing the same thing,
but one can ask it not to do so by adding

  fsset nfs none

to /etc/gamin/gaminrc

and it behaves.  The problem then moves to nautilus itself, which acts
as if it's not satisfied with the gamin's lack of up-to-the-second
response and tries to do it itself.

Anyone know of a way to configure nautilus to behave?  The alternative
is to annoy my users by making them all switch to kde instead, but
that's better than letting gnome DOS my nfs server.

       thanks,
       Alec

PS - SL5.4, although it also happened (with less dire consequences) in
SL5.3.
