We're about 70 users using ONLY Kerio Webmail, and they're tired of his slow performance.
(Server: PowerMac G5 2x1.8Ghz 2.096 Ram 2 x 250Gb HD)
(Clients: Imac G3 80%+ Imac G4 20%)
(Both with Mac OS X 10.3.8)
We're looking to install Entourage on every computer but we want to know before if IMAP performance is enough good (with 70 users).
I suppose the ranking would be:
Webmail (the slowest)
POP and working on PST files (The fastest)
If IMAP performance isn't enough good, I think we should go to POP configuration.
Tell me about your experiences.
We prefer avoid client software to mantain easy configurations , but if we won't have chance...
P.D. : Simple Webmail on 6.1 beta 5 look great and fast, but we don't know when they will release it (our users start to get nervous with performance). Anyone knows something about it?

I have been told that 6.1 will be out by beginning of July.
(However originally they told me it would be last year so I too wouldn't rely on this info.)
I would say the performance problem probably has something mainly to do with the relatively slow client computers (especially the G3's). Additionally, OS X doesn't make an especially high-thoroughput server environment. Don't get me wrong, I love OS X, and it's my favorite environment, but it's crap for thoroughput performance.
You might consider testing KMS on a Linux or Windows server and see if there's much improvement. We run 2,000 users using IMAP on a dual P4 2.8ghz Windows 2003 system and I would say we could probably safely double that before I'd get worried about server resources.
