My analysis, after talking to the people in neighbour departments
who had no such problem, is:

As Solaris NFS server is trying to validate each single access,=20
it depends on fast name and user etc. resolving (for us, netgroup
resolving is one of the culprits).

The Solaris NIS (not nis+, I don't know about that) server is definitely
too slow to serve a Solaris Ultra10 serving some 20 NFS clients.

Adding 2 slave servers solved the symptom for me. (One department was
running a couple of slave servers, the other had a SunOS4 machine as the
NIS master server.)
