Disabling unused rules

Hi,

I've had a look on my log files generated by spamassassin and half of
the rules found in 50_scores.fr are almost never used.

So ofr all these rules I've had a
score the_rule 0
In my local.cf. The file local.cf is used by spamassassin.

My question:
	-When a score of 0 is put. The rule is really bypassed by spamassassin ?
	-Such thing is effective for performance ? I didn't notice a
difference. My amavisd processes have same size (50 Mo in memory) and
process time seem to be the same.


Regards.

Yes, the score 0 rules really are bypassed. However, removing a few rules 
from the ruleset will not significantly impact SA's size. You really need 
to add/remove a significant volume of rules to impact SA's running by more 
than 1MB. Bigger factors for most folks are bayes and awl database sizes.

Yes.  Rules with a score of 0 aren't run.

Yes and no.  Your system won't spend time running the rules (most of
which take almost no time at all), but the rules are still in memory.
