I disagree. That IMAP/LDAP work happens *every time a user clicks,* not just on the initial login. Something else is going on here. What's different about the login process versus any other click? 1) A PHP session is created. (Unless you visit the login page first, in which case, it happens there.) 2) 3 pages are requested instead of one: webmail.php, left_main.php and right_main.php. 3 times the PHP for one request could very well be the problem. 3) Anything else? I don't think anything significant happens...? > You asked so I will tell you.

I think the problem Lesli's running into is simply a matter of concurrency: when the concurrent user pool is low, so's the load average. Higher concurrency, higher load. 500 concurrent users (in other words, 500 page views (not hits) a second) is a *lot* of traffic for any single box to handle. On our pool of 5,000 users, only about 1100 a day use web mail, and then, the connections max out at about 15(!) concurrently. At this point, each of our three load-balanced boxes sits at about 40%.
