Canary times
Figure 5 shows sample results for the tested server when running a typical canary script. Individual
user response times are shown in blue, with a yellow line depicting average response times.
HP analyzed this figure to determine when response times began to increase markedly and
consistently over a baseline level, indicating that user response times had become unacceptable.
Figure 5. Canary time values show that user response times started to become unacceptable when 514 Heavy Users were
active
Figure 5 indicates that response times were acceptable when 487 Heavy Users – the optimal number
– were active.
However, more users were able to log on up to a maximum of 739, limited by lack of CPU resources.
32-bit test environment
HP ran a performance test using a workload based on the Heavy User profile. Figure 6 shows select
Perfmon values during this test run.
