Performance between SpamAssassin 3.2.1 and 3.2.2 and 3.2.3

[Rose, Bobby]

My change was done last night before I knew about this dns async issue
that was introduced in 3.2.2.  I know I saw mention of the async issue
with ASN but not DNS in general.  I'll try patching 3.2.3 later today
after I've confirmed that that is where the delay in SA is coming from.
It appears to be resolved after I made my change which I only made based
on the changelogs and after diff'ing all the SA pm to confirm that there
weren't any changes elsewhere that replacing Dns.pm would effect.

I'm just surprised that no one else isn't noticing the performance
differences based on MailScanner processing times between versions.

Oh, I would have tried 3.2.3 with the aforementioned patch to see if
that made a difference too, because that patch will end up in 3.2.4.

Is there any chance that you can do that?  The patch affects more than
DNS.pm, though.

If there's still an issue on 3.2.3 with the patch from bug 5589 then you
should add a note to that bug and raise the issue on the Spamassassin
Users mailing list too.

Cheers,

Phil
