Elguapo is right--my observations show the client is slow Thanks Elguapo. That is indeed what I was saying. I see the same things in Google Maps as I do with Zimbra, so I don't think it is a Zimbra thing. I think, compared to a fat client like Outlook, an AJAX client is just going to be a bit slower--especially when using imap instead of mapi.
I do think it will scale better--an equivalent Zimbra system seems like it would be slower in general (even on my jacked up pc it seems about 10-20% slower than Outlook), but stay the same speed under twice the load (on the server) that would start showing drastic speed issues on an Outlook/Exchange setup. Plus, it should not have any of the problems Exchange setups exhibit--file system corruption, logging commit problems, fragmented database, message store size limits, croaking on large attachments, etc. ad nauseum. Don't get me wrong--Exchange+Outlook rocks for small to medium setups as a groupware solution. Expensive, but very nice. Zimbra, however, has the possibility to easily surpass it in features and #users per setup.
Zimbra looks like it will scale better horizontally too. Adding another server to a Zimbra "cluster" looks easy and would allow another 1-3,000 users pronto. |
