After upgrading to cyrus-imapd 2.2.10 yesterday on my pilot server, I've noticed a major slowdown in how the server responds to the LIST command. Previously, when running 2.1.17, the LIST "" * command usually returned all the mailboxes I have access to within a few seconds. After upgrading to 2.2.10, it looks like it is now taking about 30 seconds to return the mailbox list on a server with 12000 mailboxes, with about 1500 of them shared.
Has anyone else noticed the slow down? Any suggestions? I grokked through the source code but didn't notice anything majorly different in the mailboxes.c or mboxlist.c. I didn't bother going through the database backend since I am using the same database (skiplist) format as my mboxlist backend. --- 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
