Wondering if anyone out there is running a LARGE Cyrus user-base on a single or a couple of systems? Let me define large: 25K-30K (or more) users per system High email activity, say 2+ million emails a day We have talked to UCSB, which is running 30K users on a single Sun V490 system. However they seem to have fairly low activity levels with emails in the hundred-thousands range not millions. So far that's the only other place we've talked to. Everyone else seems to spread out 5K users on a large number of backends. We have 60K users, and were trying to run them spread across 2 systems and ran into problems when Fall quarter started and the load just skyrocketed. Email volume today 3.6 million. ---- 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
