I have a relatively big installation here in the university, 1 mail
server for 10.000 daily active accounts.
I converted from maildir to mdbox + zlib in march, and these are my
considerations:
1. CPU is not a problem, even delivering more than 400 messages per
minute (blade HS21 with 2xQuad E5430 from 2008)
2. I used dsync to convert from maildir to mdbox, with dovecot 2.1 at
the time.
The biggest win is the file number reduction, from 27 million to 2 million.

Hi,
I run a small IMAP server for a dozen guys in the office, serving
about 55GB of Maildir. I recently became aware of the Zlib plugin (
http://wiki2.dovecot.org/Plugins/Zlib ) and wondered
1. given that there is about zero CPU load on my IMAP server, is
enabling the plugin a no-brainer or are there other things (except CPU
load) to consider?
2. For enabling the plugin, I suppose you compress all the existing
mail just once and then add 'zlib' to mail_plugins in order to have
all future incoming mail saved?
Any insight by people familiar with the plugin would be much
appreciated - thanks!
