I posted earlier today about a performance issue I'm seeing with cyrus-imap 2.2.4 (and 2.2.5, I attempted an upgrade)... A basic summary from before:
- RedHat Enterprise Server 3.0 - Upgrading from Redhat 7.3 - Cyrus 2.2.5 - Upgrading from Cyrus 2.0.16 - Pam auth through sasl, authenticating against a mysql db - Running SMP on a dual processor machine. RedHat Enterprise Server comes with libdb-4.1 installed The server seems to function fine, just slowly... I've run local imtest -z runs on the server, and I've seen finishing results on the order of anywhere from 40-60 seconds. Running the same test on a RH 8 server , running cyrus-imap 2.1.something, with similar authentication routines took 3 seconds... so I'm feeling pretty confident that the auth method is not slowing things down to this extent. I read some not-so-clear comments in the archives that mentioned very bizarre libdb-4 issues, with redhat distributed libdb-4 (or maybe I'm remembering incorrectly), especially with threading issues. Seems threading issues could cause really slow performance... Does this sound like I might be on the same track? Any other ideas that I might try? Unfortunately, the server got placed into production before we noticed the performance problem! --- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
