It is likely that the user tasks also eat up CPU cycles because the service is on. Turning off the service not only eliminated the 5-8% of the service, but the small amounts that many of the processes of the 75 users are using. Due to the way that the Task Manager does it's math (it truncates 1.999% to 1% rather than rounds) even a miniscule change can sometimes have a big impact over a large number of processes. tim -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx]On Behalf Of Erik Gerard Sent: Tuesday, April 22, 2003 2:07 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Norton Anti-Virus & Processor Utilization With 75 test users logged in, TaskMan indicated that rtvscan.exe was using = 5-8% of the four processors. When I stop just the NAV service, processor = utilization drops 20-25%!=20 I need suggestions.
