Not that many, if I exclude reading the uidlist file contents. See the

SELECTing a mailbox has nothing to do with FETCHing messages, so above
I tested this by timestamping tcpdump output while issuing this command

It will be nice if the "SELECT MyMailbox" command will be "SELECT
mymailbox LIMIT 100" or something, to get the first files since only the
last messages are shown to the user.
I don't know if "Limit" clause is available over IMAP.

I straced dovecot and of the whole request/response process, around 30ms is
