I saw some issues like this for a while, months ago, but concluded that it was a 
Thunderbird issue rather than a Dovecot issue. For diagnostic purposes, can you try 
Outlook Express and see whether the same operations go faster?

There are some strange IMAP and mail-server-related settings in Thunderbird - not well 
documented - which might be worth experimenting with.
