I have several clients with GW8sp2 and just this one is seeing a very slow response at the client.

Backend - OES2sp2a-Linux (latest patch set as of 1 week ago), Clustered to a fiber attached HP MSA SAN.
GroupWise 8sp2 on server and client.
Client PCs XPsp3 - Novell client 4.91sp5

when people are typing email, the system will suddenly stop showing the text. It is possible to get almost a full line of text ahead of the system before it shows the text.

Any ideas/suggestions on what to check, or change?
