Is this all Linux SMP installations, or just those using NPTL?

Ummm, we've successfully used Berkeley DB on SMP systems since DB3... Is
there a reference to what problems this causes anywhere?

Ok, this is getting interesting. Are there known with db3 on SMP
system? We use the stock db3 rpm from RedHat 7.3 (3.3.11) on an SMP
machine, and we seem to have database corruption problem on
mailboxes.db.

In /etc/fstab, specify the "noatime" option for the partition on which
your mailspool reside.

Oh. Yeah, that is a scenario where Courier might just be faster than Cyrus.

Hah, I bet he had Cyrus on a partition (or directories) operating in sync
mode :) (I assume he had a 2.x Cyrus install).

Deliver 4-5k messages to a single mailbox and then delete message
10,100,1000 etc. Do that for 1000 users at the same time.. Then Cyrus
really starts to perform!

This rings a bell.
His test system is a Pentium 200 with less than 10 users and just auto generated
test messages. The mail boxes were growing to 20-30MB...at least with the
Courier setup.
Any other info would be great and thanks for the note.

Folks I need a bit of feedback and insight.
A co-worker of mine is implementing an IMAP server here and has decided to ditch
Cyrus after he thought it was too slow and could not configure it. That being
said, I don't want to address the configuration issue. I am interested in the

Another thing I forgot to mention - you might try linking lmtpd
static to reduce per-instance startup costs. (This may not be
an issue if setting prefork non-zero causes the lmtp daemon to
fork for each instance instead of the master forking and then
execing lmtpd.)

Pat,
I'm not seeing any evidence that postfix is batching up the local
deliveries through a single lmtp instance... I've made some changed
recommended by others using postfix, but still don't see evidence of this
