I have had PRESCAN OFF for a few weeks now, and have not noticed much of an increase on my servers, but I was not near capacity anyway. Bill, I've got a handy app from Passler that provides me with nice graphs including processor utilization that I am sampling every minute (minute averages). I just turned PRESCAN OFF a short while ago and it's actually a bit worse than a 25% relative increase on my system. My hourly average went directly from 33% to 46% with PRESCAN OFF, which is a 39% increase. I've attached an image of the minute averages with a green line marking the point when I turned PRESCAN OFF. Take note that I run both F-Prot and McAfee on my system, so systems with only one virus scanner won't see the same degree of a jump, though it should be rather large. On systems with plenty of capacity, this is not a concern and the increase would be not very noticeable despite being relatively high, but I would like to fill this box to capacity and add more, but not before I have to.
