I think there are several theories on SA processor usage.
1. bayes expire
2. bayes expire jorrnal bug
3. Some rule with something like an .* in it that is looping like mad on
certain text patterns.
4. Something else.
If you are getting suddenly huge bayes journals along with your processor
usage, it is #2.
If SA is taking 2-5 minutes randomly, and repeating on the same mail message
doesn't have the same result, it may be #1.
If SA is taking a long time to process a specific message every time, it is
probably #3.
The first thing is to try to determine whether you are seeing spikes or
constant heavy load. I think you are implying that you see spikes.
The next thing to do is to try to figure out of the spikes correlate with
certain messages, with certian times, or occur randomly. You can also check
for the bayes journal bug fairly easily.
If you end up with a particular message that eats the processor alive, you
probably also have a bad rule that is the real culprit. DProf I believe it
is should perhaps be able to track the problem down to the rule if you have
an example message.
