This definately speeded up TB, but screwed up sending mail completely for me, just FYI

To make sure TB keeps nothing at all on the machine, follow these steps after adding your IMAP account. I don't use POP 3, so don't ask me about POP 3. I also give instructions on how to empty your trash when closing TB automatically.
1. Open Tools.
2. Open account settings.
3. Expand the main account tree view you want to change.
4. Go down to synchronization and storage.
5. Press tab once. NVDA will speak for a while, but you will land on the keep messages in all folders on this machine. Uncheck it.
6. Hit OK.
To empty your trash on exit...
1. Repeat steps 1 to 3 above. Hit Tools, account settings. expand your account tree view you want to change.
2. Go to server settings.
3. Tab until you hear a storage category. 2 check boxes will be here. Empty inbox on exit and empty trash on exit.
4. Check, empty trash on exit.
5. Hit OK.
