How to estimate the memory usage in cyrus imap 2.4.X ?
Mailbox size is Important ?
For example 5000 simultaneous IMAPS in mailboxes with 2Gb size.

One small curiosity is that the memory use per IMAP session seems
to have increased dramatically. I'm looking at the output of the
Linux "free" command after buffer cache has been subt
