When we had a serious load issue we found that upgrading everything possible
made a difference. Even some of the Perl modules in use might have made a
difference. We're now tweaking it all bit by bit to reduce load where
possible.
There are a couple of handy tips in the MAQ that might help if you haven't
looked there already

I ended up turning Spam Checks off for some of the domains that I'd rather
not even be hosting. Maybe this will be the spur they needed to move along
:)
After doing so, load is back down below 1.00 After upgrading to the latest
stable, it did reach over 100 and my box was crawling!!!
