Stuart-
Not significant that I have noticed. We are running a dedicated
spamassassin gateway
however. It's only job is to process spam. It is running dual Xeon
2.80GHz/2MB cache with 4GB of RAM over RAID5 with some scratch partitions
loaded in RAM. We also run clamav, mimedefang, bayes out of mysql, and
milter-greylist on the same machine.
We process 15,000-30,000 emails a day on this machine.
One thing that could be improved would be to add which directory the
plugin uses as scratch. I would put this over into my memory based
mounts and that would at least lower the I/O overhead.
