One reason for slowness is a missing call to {async}->set_response_packet
in Plugin::ASN, which leds SpamAssassin think the request never arrived
and waits until timeout, even though the response does arrive (quite fast
usually).
See
http://issues.apache.org/SpamAssassin/show_bug.cgi?id=5589
If you care to try out the fix (which is rather extensive), you may
apply to 3.2.3 (or 3.2.2) the patch attached to that bug entry.
