Cyrus gurus - can you help us diagnose the IMAP debug below that I gave and
help us understand the slow down. I am no imap pro, but the imap_debug
below seems to show a lot of in-and-out's for a single message click. Again
this is roundcube, centos 6, kolab 3.4, cyrus version:

name       : Cyrus IMAPD
version    : git2.5+0-Kolab-2.5-108.1.el6.kolab_3.4
vendor     : Project Cyrus
support-url: http://www.cyrusimap.org
os         : Linux
os-version : 2.6.32-042stab108.7
environment: Built w/Cyrus SASL 2.1.23
             Running w/Cyrus SASL 2.1.23
             Built w/OpenSSL 1.0.1e-fips 11 Feb 2013
             Running w/OpenSSL 1.0.1e-fips 11 Feb 2013
             Built w/zlib 1.2.3
             Running w/zlib 1.2.3
             CMU Sieve 2.4
             TCP Wrappers
             NET-SNMP
             mmap = shared
             lock = fcntl
             nonblock = fcntl
             idle = idled


See below for all other comments. Again, this is all regarding bug:

Mike - not exactly sure what those mean on the line, I will consult with
them in a few minutes. You know, I'm not even sure it's the SPEED of cyrus
as much as the LOAD it gets put on it from the multiple check in's and etc
etc. I've posted my IMAP debug on the bug and I'll post it here too:

They're telling me the multiple check-in's with IMAP is costly. I am not a
imap dev, sorry - didn't get much more than that. Another guy suggested
cache wasn't working right, but I watch things update everywhere they're
supposed to regarding cache (especially in the kolab cache mysql table) so
that looks well. The Mysql log shows a ton going on for a SINGLE message
click. Look at the mysql logs I provided.

You (as many others) may not think your install is slow, but I am telling
you, just go in, disable the plugins I have explained, and give it a shot.
Watch your message load increase by 10x. Christian (CC'ed) tried this, and
it worked awesome for him as well. Of course this isn't perfect/permanent
and you can simply re-enable the plugins, nothing will happen to your
install. I would at least try it and you'll see what I am talking about.
Maybe you just aren't used to the fast actions on mail servers like I am.
Give it a shot.

I am going to say user and sys on USAGE is probably the timing numbers to
go against. Let's see what cyrus guys CCed on this have to say.

What's your entropy at? Is it headless?
