My first suggestion to anyone who is having problems with SA running
slowly is to check memory usage.
You posted previously that your conf file contained this:
SPAMD_OPTS="-m 25 -H -u mail -D"
"-m 25" means that you are running 25 spamd processes. On my system
(with a few extra rulesets), the spamd processes take up about 60-70M
each. How much memory do you have? You need to make sure that the
machine doesn't go into swap. If it does, SA will slow down
dramatically. Try running the "free" command to see how much memory you
have available. If you are close to the edge, you may want to lower the
number of processes.
"-H" is a command to change the home directory and generally requires an
argument, so I'm not sure what it's doing here.
"-u mail" means spamd is running as the user "mail". So when you are
testing, manually learning the Bayes db, etc, make sure you are logged
in as "mail" so that you are using the same settings and databases as spamd.
"-D" puts spamd into debug mode. Aside from filling up your logs with
excess debug information, this will probably slightly increase the
memory use and slow down the scanning process. If you don't need it for
some reason, get rid of it.
