Have you tried exporting all messages to the Powermail format, them starting with an empty email db (all messages deleted- do have a Back up copy!) them import those messages back in? Sometimes that can "clean" a database. I've done that with FileMaker Pro before.
Do you have the spotlight searching enabled? try turning that off. (or on, whichever it's not).
