We had some performance problems with NFS under Digital Unix.
Our NFS server runs Digital OSF/1 V3.0. We have clients
running Ultrix 4.4, Solaris 2.4, and Digital Unix 3.2C.
The 3.2C clients were often slow and got a lot of
NFS server not responding
messages. When we updated one of our Sparc's to Solaris 2.5,
we noticed that it also got slower. Since we knew that one
of the enhancements in Solaris 2.5 is the update of NFS from
version 2.0 to 3.0, we wondered if NFS version 3.0 was the
cause of the performance problem. We decided to test the theory
by having the Alpha clients use NFS version 2.0.
So, we modified /etc/fstab on the clients by adding the option
nfsv2, as in
/src_at_woodfin /woodfin/src nfs rw,bg,nfsv2 0 0
The difference is very noticeable. The Digital Unix clients
are now much faster! Students are beginning to use the
Alphas again.
However, when I modified /etc/vfstab on the Solaris 2.5
client to make it use NFS version 2.0, our Digital Unix
server paniced. I guess there's a kernel bug out there.
So, don't try this on machines running Solaris 2.5!
