Is it possible to

If anyone is interested the issue seems to have been the extra rule sets added to the scanning of clamav. After removal of all of the extra databases the system was able to handle the loads 100%.  

Couple of items I had to change.

I had to drop the Max Children = setting in Mailscanner.conf to 3 as these systems only has 3 gigs ram and then I was able to add the Sanesecurity extra rule sets back with no issues..

As soon as I added the Securiteinfo: rules back into the mix the system started to have problems.

Note: might be an idea to move this off-list or to clamav-users or to sanesecurity list but for now....

This is a slightly unfair test but I scanned a small file with each database and all returned an OK but here are the timings for each database...

If you are using any of the ones marked [Possible Performance Issue] then removed them first and see what happens.
