[rt-users] Serious performance problems

Dear Sirs,
we do run RT 3.4.2 on Debian Sarge and Postgres 8
We do have 20 users and 2500 Tickets at the moment.
There have been performance issues ever since, but we blaimed them on the shared server.
There shell be 10 new users in nnear future.
Now we moved to a brand new PC Server with contemporary hardware (it is powerfull).
Still opening ticktes, replying or creating tickets takes sometimes 10- 20 seconds.
I have scanned the RT Lists and found some hinds.
Since we are under pressure i would apreciate if someone has mastered these problems and can give guidance what is to be done. What is most promising to concentrate on (database, Perl, DBI::Search?
Please help us make our RT the lean fast and handy tool we need it to be!
I attach the system report for an overview to libraries etc.
