Hello listsince beginning of this week we use the new spamassassin 4.0.2 Since then we can see that processing time (at least for particular mails) massively increased. We use a timeout of 30s in our setup to communicate with SA. Two mails we now have that cannot be processed anymore in that time and therefore get stuck in our processing. Mail A has a huge load of links/mailtos in header and body. About 7k. The timing in processing with the very same rules is from 6s (in 4.0.1) to 2.5min (in 4.0.2). I counted the number of URI spamassassin detected and the number of DNS queries in both versions and they are more or less equal. So I guess the increase in processing time is not DNS related. Mail B does not have that many URI but a quite complex HTML attachment with a load of styles with almost every div and span tag. The processing time is 4s (in 4.0.1) and about 1min (in 4.0.2). I will check in our timings logs to see if we see a general increase in timings or if it's more only related to specific mails. Have a good one
Hi, one commit that can degrade performance is this commit https://github.com/apache/spamassassin/commit/4a6643c72fe5cd6296b2e67eb0ccc368a4987caa This tries to find CNAMEs for all hosts found in the email. From my tests this can slow down email processing a bit but not that much. Could you send me those emails in private ? Thanks Giovanni
