So you have no problem with settings as low as this? What is the primary method of access of you Zimbra? Is it Web Interface or is it POP/IMAP ? I'm curious because ours is mainly Web Interface (out of 300 people at least 200 using Web Interface). And we had our thread numbers bumped. Now I start to think threads are not the issue. > Have you checked out this... > http://wiki.zimbra.com/index.php?title=Performance_Tuning_Guidelines_for_Large_Deployments yes, that's what we were following including bump in number of HTTP threads on mailboxes. But apparently out-of-the box is just fine, according you your numbers. Thank you for that information. -- Dmitry Makovey Web Systems Administrator Athabasca University (780) 675-6245
