How did you determine that MailScanner dropped in performance? Exactly
what characteristic are you seeing a problem with?

You'll have to run the vmstat for a bit to be sure there really is no
swapping, and perhaps look into the sar command (think it's part of
the sysstat rpm or something similar.... I ditched my last RH9 the day
after the desupport notice.... (a while back:-), so my recollections
of exact package details is faint, to say the least...)
sar will help you (together with top) to determine if you have unusual
CPU load, which might be an indicator.... For IO, find and use iostat
in a similar way as you use vmstat.

Until you have some facts, it's way to soon to start assigning blame
to individual systems/processes:-).
