only half of the problem solved -- cyrus deliver slow

[Su Li]

I tried set sendmail configuration to deliverymode=queue. and use "sendmail
-db" and "sendmail -q1s". I got the same through put. I using sendmail
8.11.6, will that effect the through put the email delivery of cyrus imap?  

I did went through the configuration of sendmail about cyrus. But I still
get:

cyrus     3645  3644  0 13:17 ?        00:00:00 deliver -e -m  --
loadtest510

Is that the process that you was talking about, which is not good for
performance? If yes, what should I change?

Thanks a lot,

Su

What version of Sendmail are you using? You want Sendmail 8.12.4 or
later. You should consider running Sendmail in deliverymode=queue with
frequent queue runs if you want the best possible performance. (Take a
look sendmail/TUNING in the Sendmail distribution.)

You should also configure Sendmail as described in the Cyrus
documentation, using LMTP delivery to Cyrus. You don't want "deliver"
processes---it's a completely unnecessary fork.

There's an Addison Wesley book on "sendmail performance tuning" soon
to come out that might help you with this. I'm going to be receiving a
review copy and I'll report on it.
