Mark, We found that for uvscan, using RAMDISK cut the scan time by anywhere from 1/2 to 2/3 the scan time of using sigs on HDD. No difference was found for clamd. The tests were run on a Sparc w/ 2GB RAM, with a LA around 3, and a context change rate around 3K to 4K/sec, and a page rate of next to zero. I suspect that if you try this on a system with any degree of paging, that your results will not be as good. Hope this helps! Jon -- Jon R. Kibler Chief Technical Officer A.S.E.T., Inc.
