Hello,
I'm doing some perfomance testing of our dbmail instance. I noticed that If I
copy large number of mails into single folder, append starts to get really
slow. For example, I have a spam collection of more than 50k sitting on a cyrus
imap comfortably in a single folder with append to it
My blind shot is that it doesn't depend on dbmail itself, but to MySQL
"filling up".
Things probably get slow when either:
* your controler cache gets filled and the controller starts writing
for real to disk
* your InnoDB log buffer gets full and the DB has to start committi

Well, obviously it the depends on the mail amount.
We have about 1000 mailboxes with about 350GB of online mail. On spike
hours we have a full recycle of the logs in about 10 minutes especially
because of circular replication increasing the server activities.
Restart after a crash takes more
