>From elementary queueing theory: If "U" is the utilization of a "server" (CPU, link, network processor, etc.) then the mean delay is proportional to 1/(1-U) and the variance in the delay is proportional to 1(1-U)^2
I try to keep my machines running around 70% to 80% per core. Bo -----Original Message----- From: Ophir.Prusak [mailto:[email protected]] Sent: Tuesday, October 08, 2013 9:01 PM To: [email protected] Subject: Is my load server causing results to be in-accurate? I'm running a JMeter test using JMeter on an amazon EC2 instance (large) as the load server using 1,000 threads. The load server CPU is steady at about 90% utilization and memory is at 70%. Is there a rule of thumb regarding at what point does the server not having enough resources impact test results? Regarding CPU would you say 90%? 95% 99%? Regarding Memory would you say 90%? 95% 99%?
