Craig: Here's a nifty little tutorial on using the Windows Server 2003 performance monitor to set up a daily log to log system performance and utilization: http://www.computerperformance.co.uk/HealthCheck/FirstLog.htm.
It might help you pinpoint what's happening when. Just another Mr. Obvious thought - Do you have antivirus software on your server? Is it possible it's scheduled for a time somewhere around lunchtime? A long time ago in a galaxy far, far away, I set up a Remedy server for a site that had this problem. They ran antivirus from a parent server, and the parent server dictated that scans be run at noon (when users are at lunch). Of course, I didn't work fulltime at this site so I wasn't aware of their antivirus configuration. The scan would kick off and then take several hours to complete, gobbling up processor and disk access. Someone finally complained about the slowdown and I requested that the server be added to an exclusion such that antivirus would be kicked of at 2AM rather than noon. -----Original Message----- From: Action Request System discussion list(ARSList) [mailto:[EMAIL PROTECTED] On Behalf Of Craig Carter Sent: Tuesday, January 15, 2008 12:27 PM To: arslist@ARSLIST.ORG Subject: Re: Server Configuration Recommendations ** Hi Phil, I believe it is RAID 5 and there is a lot of disk I/O but it doesn't seem to be excessive. What tools do you recommend to evaluate that other than Task Manager? It's a progressive thing-the more that log in, the worse it gets so I'm more inclined to believe we have some excessive database activity. I'm getting tired of getting beat up by the users so I'm looking for any recommendations of things to look for. Good to hear from you, Craig Carter ________________________________ From: Action Request System discussion list(ARSList) [mailto:[EMAIL PROTECTED] On Behalf Of Phil Murnane Sent: Tuesday, January 15, 2008 11:08 AM To: arslist@ARSLIST.ORG Subject: Re: Server Configuration Recommendations Craig: What does the server resource utilization look like when you go from 80 to 100 users? Is there lots of paging or some heavy disk I/O? I'm sure you've looked in this direction, but perhaps we can offer a fresh pair of eyes. One thing I've seen kill database performance is if the DB is stored on a RAID 5 volume and there's lots of write activity. If the database starts looking like the bottleneck, this might be something to pursue.
