RE: [Declude.Virus] Performance Issues

Thanks for the feedback, and how about the disk i/o ?   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mitch Hegstad Sent: Wednesday, March 03, 2004 10:23 AM To: [EMAIL PROTECTED] Subject: [Declude.Virus] Performance Issues   This is my second message on performance issues.  Following is feedback I received from an administrator at our host. I simply asked for feedback on declude –   Yes, it should work.  Just be careful when you set it up.  Alot of administrators that use Declude have it set up to send virus notifications to any sender that sent a virus.  The problem is, the address of the sender is not necessarily the same address the message is sent from.  Our postmaster account gets these notifications all the time, usually with some sort of snarky message about how we need to improve our virus scanner, when we actually had nothing to do with the infected message.   You'll probably also see a slight increase in processing time.  Usually, scanners like this run the virus scanner on each individual message that comes in.  This causes a large increase in CPU usage and IO time. Normally, this isn't anything to worry about, but is still something to be aware of.  When we used a similar system, our delivery times went from 1 second without scanning to as long as 1 minute.   I’m concerned with the disk i/o.  Although we have some spare cpu cycles, our disk use % often hovers around 40%.  An increase in disk i/o could open a whole can of issues.   Any feedback welcome,   Mitch
