100% processor utilisation

[M. Schievink]

We use ClamAV 0.67 as virusscanner.

It hardly takes any time to process messages, only a few seconds total.
So I think the processor does something, but nothing that it should be
really busy with.

So basicly everything works okay (as in the mails get scanned and
delivered fast enough), but MailScanner just seems to do something that
makes it go to to 100% processor utilisation.

I'll take a look at the beta.

how long does it take to process messages - that's what you should be 
worrying about. Processor utilisation just means it's chugging along 
doing something but it might not be really really busy..its kinda 
complicated with a real O/S (ie non windows) to explain..

There where some code changes around the beginning of 4.28 version in 
order to catch the virus in encrypted zip file and other issues that 
seemed to slowed the processing down for some people.

Worth checking out the 4.29.1 beta, it does seem quite a bit faster on 
my system.
