Kami, Is your DNS that IMAIL/Declude uses local to you? Or are you using an upstream DNS? That many IPV4 tests may warrant this. We noticed a large performance boost by using a DNS on the local LAN.....
Just a thought.... ----- Original Message ----- From: "Kami Razvan" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, June 04, 2003 3:58 PM Subject: RE: [Declude.JunkMail] Declude Processes & Server Load I truly wish I could explain it.. May be I am dreaming.. But what I see is Declude does not get to 100% CPU since we moved it to IMail to do IP4r. This morning for example I saw about 10 or so Declude processes.. One at 19%.. A lot at 0% and then jumping to 10% and going away some hit 100% for 1 second and disappeared. Before we were seeing 100% CPU staying for several seconds and then each one of the waiting processes hitting 100%. We could not even more the mouse.. It would move in steps.. Now we don't have that problem. Watching this is now my favorite pass time... A cup of coffee and watching CPU & Declude processes.. Have to try it with beer.. Could be more fun.. But can't imagine anything be more fun! :) Regards, Kami -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dan Patnode Sent: Wednesday, June 04, 2003 4:19 PM To: [EMAIL PROTECTED] Subject: Re: [Declude.JunkMail] Declude Processes & Server Load Kami, I'm running ten IP4r tests, referred to in my original email as an "external DB query." There seems to be a descrepency between this as a cause and Scott's answer: > the Declude process should not show high CPU usage in this case. > Declude uses the "Sleep()" command, which gives up CPU cycles to > other programs (and will prevent the Task Manager from showing CPU > usage in Declude during idle times, such as when Declude JunkMail is > waiting for an external or DNS-based test to complete). Assuming we're all talking about the same thing, Declude continues to run as a process waiting for replies from IP4r requests but does not consume much CPU time while doing so. Does pulling out IP4r tests during an episode show a immidiate decline in CPU use? Does anyone know how the people hosting the IP4r tests feel about us slamming them with queries? Suppose I'm cruising along with 20,000 queries a day, then jump to 500,000 over a few weeks, surely that makes an impression somewhere? Is there a point were we should ask about doing more?
