I'm trying to figure out the best approach to handle virus scanning on my new mail server. The machine itself is a beast: Dual Xeon 2.4GHZ (HT) 4GB RAM U160 RAID1 (system) U160 RAID5 (storage) Originally, I was thinking that handling the virus scanning on a memory file system would be best to keep disk IO to a minimum, however, I'm unable to demonstrate the mfs is any faster than a real disk, even when copying 200MB files. This is probably due to softupdates. So, with softupdates enabled, is there any real disk IO if an email message (and it's attachments) are extracted, written, scanned, and deleted within a few hundred milliseconds? Would there be any real advantage to performing these operations on a memory filesystem? TIA, -- Troy Settle Pulaski Networks http://www.psknet.com 540.994.4254 - 866.477.5638
