Lesli st. Clair,
Sorry to hear about your pain and suffering. Although
I have only fractions of expertise of the much more
qualified people on this list and My load is only
about half of yours, are you married to iPlanet IMAP? I use Courier and it seems to be holding up nicely,
although we only have ~75-100 users at the time.

Hi All,
I've been struggling with SquirrelMail for two
months. At about 300 users, the CPU is maxed out and the load average on
a dual-Ghz CPU Sun machine climbs into the 80s. I moved it to a larger,
4-processor box and did load testing with software. It appears that the
4 processor machine would handle the load, but I can't be 100% sure--and
I really don't want to put the user community on it, and then have to
back out again.
I've tried every tuning tip, and what I still see is
huge jumps in CPU usage with every login, and I can certainly push the
load testing software to break even the 4-CPU machine.
So, I'm here one last time hoping for some answers,
perameters, hardware specs, anything before I give up.
I can put it on a dual or quad CPU sun box, with
plenty of RAM. I have used both PHP acceleration and the IMAP proxy. On my
current system, users login about every 12 seconds, on average,
during busy periods. We use iPlanet 5.2 for IMAP (which does not do server
side sorting and threading).
Our community has about 6000 students, who are the
primary users of webmail. simultaneous users probably hit about
400-500.
Any other iPlanet IMAP users out there? Any last
advice before I ditch SM? Any other load issues out there?
