But this is obviously where amavisd-new spends half its time.
Ahhh ... so we need a better pool of LDAP servers. Yeah, our LDAP
servers are overloaded.
You might try to make better indexes on the LDAP server before upgrading
the hardware.
Unindexed LDAP queries are very expensive! If you use a SunONE-based
LDAP server its log shows unindexed queries with a "U" at the end of the
line. Don't know about OpenLDAP, and there are too many versions around...
I also hacked into amavisd script and commented out unnecessary LDAP
queries, that we will not need. I am now only checking for
[EMAIL PROTECTED] and [EMAIL PROTECTED] . Lines involved are 2207
to 2228 in my 2.3.1.
Mark, would it be possible to add options in amavisd.conf to configure
which queries should be done? So that unapplicable ones are skipped.
The output of a script that breaks down TIMING lines tells me that:
lookup_ldap: 962893 ms total; 5888 times; 163.534816576087 ms average;
38345 ms max
amavisd and LDAP server and MySQL quarantine are on three different
machines. Still have to figure out why a peak of 38 seconds!
