we are running:
server: GW8 HP1 on SLES 10 SP2, OES2 SP1
clients: Win, GW8 HP1

Some of our problems are:
1. when any user starts Find POA, CPU utilization goes above 95% and never goes below it
2. Find tool is slow and not reliable (for instance: it can not find some mails/appointments if Subject is criteria, but finds it if different criteria is used... )

We have done reindex (POA HTTP console - Configuration - QuickFinder Indexing, Unlimited...) many times -:(
