Re: MURDER : tuning for increasing load

[LaurentG]

In fact, 100 000 users represent more or less 600 000 folders & subfolders. The choice of murder is high availability, even if one backend falls down, only 25% of the users will loose the mail service. Each server has 2 CPU & 5 GB RAM. Any idea on optimizing Berkeley DB cache? Laurent. John Madden a écrit : I have to deal with increasing charge of by now 500 users that will grow up to 100 000. All mailboxes exist, for a 65Mb mailboxes.db on mupdate Is murder even necessary for such a configuration? Based on the numbers on Cyrus' pages, I assumed 200k accounts on one big, beefy box would be ok (and management more easily swallowed "4 CPU box with 8 GB RAM" than they did "lots of little boxes.")
