Hello. I have cyrus imapd runing now on my server. Today I heard people say when the user number exceed 5000+ the cyrus proformance drops in the way that unless many partitions ware made (what partition? file system partition?) to share the load. I'm pretty newbie on mail server administration, should I start to do something in case my user number grow over 5000+? I'm running a dual-processor Xeon server with IDE soft RAID10 discs.
By number of users, do you mean concurrent sessions or number of inboxes?
I don't know of anything that will cause cyrus performance to suddenly bottom out after 5000 inboxes -- especially if you are using fulldirhash.
The number of users you can support on an individual machine is mostly related to its memory and (especially) I/O capacity, and the number of *concurrent* users, not the number of inboxes.
