[Dovecot] M-Box benchmark

[Gerhard Wiesinger]

Hello Timo!

UW-IMAP is even slower on EXPUNGE (factor 10 I guess, nearly on every 
operation).

Dovecot with large files (2GB, e.g. new mails on the end) is really 
perfect on EXPUNGE (when there are no large holes). It takes <1s to 
EXPUNGE.

Ciao,
Gerhard
