We run Cyrus 2.3.11 + Fastmail patches as of January 2 on a 64 bit RHEL 5.1 Opteron server. We have some 1000 users and up til 300 simultaneous imap processes. The system works nicely with MUAs like Thunderbird and various flavors of Outlook and shows no signs of any significant load. We do, however, have users using the Oracle Outlook connector who complain about bad performance. I've set up a testaccount with a 16k messages folder. Using Thunderbird, messages are shown w/o any noticeable delay when I click them. Using Outlook+outlook connector, the message 'getting complete message' are shown for at couple of seconds before the message is actually displayed. This may be what annoys the users. Are there other Cyrus sites out there with similar problems? -- Michael ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
