I have changed the mounts to to tcp and added the no_subtree_check to the
server. I have also disabled IPV6 on the desktops anyway... so far no
complaints. I am wondering if the last "its slow" complaint was justified!!
The system seems to work fine and then one of the desktops will just grind to
a halt. For example - usually to open OpenOffice takes a few seonds, this can
increase to 45 seconds when the system "plays up" and KDE can take 5-10
seconds to open a menu. Checking top I don't see much activity so its not an
issue with desktop cpu or memory resources. Most frustrating of all its
intermittent. A reboot clears the problem. It might not raise its head for
hours or even days.
The server is Mandrake 9.1 (nfs v2)
The desktops are Mandrake 10.2
I will see if I get any complaints tomorrow.
