MailScanner/Spamassassin slow after version upgrade

[Randal, Phil]

You left out a few key facts.
 
What did you upgrade from?  (MailScanner and SA versions).
 
And most importantly, which OS and Perl versions?
 
Cheers,
 
Phil

	The time it takes to process an email has doubled since Friday
(7/26/07) when I upgraded to MS 4.62.6 and SA 3.2.2.  It was around 3.5
seconds, and now it is averaging 7 seconds.

	We use DCC and razor2 - no pyzor.

	I have implemented sa-compile using re2c expecting to get a
performance boost. 

	'MailScanner --lint' doesn't show any errors, except noting that
we have clamav processing turned off (output attached).

	<<ms.txt>> 
	I have included output from spamassassin's lint command.
