[SOLVED] Are you aware you can compile your SA rules ?

Mail::SpamAssassin::Plugin::Rule2XSBody - speed up SpamAssassin by compiling regexps

The following is specific to RedHat/CentOS

1) Ensure you have installed SpamAssassin from a repo as you will need the additional binaries
2) Install re2c as root :- yum install re2c
2) Update /opt/zimbra/conf/spamassassin/v320.pre and uncomment the following loadplugin line :-
# Rule2XSBody - speedup by compilation of ruleset to native code
#
loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody
3) Compile the rules :- /usr/bin/sa-compile --siteconfigpath=/opt/zimbra/conf/spamassassin --updatedir=/opt/zimbra/conf/spamassassin

This should speed checking up for you a bit

This was an idea I've toyed with in the past, but I never could find an answer to how often you have to do this (assuming you download updates 4x/day).

You would need to perform the sa-compile after each sa-update if you wanted the optimised rules. Alternatively, SA does know when a newer .cf is in place compared to the compiled ruleset so the newer one will take precedence. With that in mind you could compile your rules once per day when server load is less busy. HTH.
