I was absolutely convinced that something was misconfigured when I saw
the LA over 80. So I moved it to anther, identical machine and got the
same thing. Then I moved it to the 4-CPU monster.
The ONLY problem was CPU. RAM, swap, disk I/O all were taking a nap.

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.
A load of 80 is usually a cumulation of problems or a few runaway
processes. It's unlikely that Iplanet or Squirrelmail is the main
contributors to the problem. You should check out your memory usage,
disk io, wait times, etc... Just remove all the reasons for the
problem.
