Canary Times - HP ProLiant DL585 G5 Performance Manual

Canary times

Figure 4 shows sample results for the HP ProLiant DL585 G5 server 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 4. Canary time values show that response times began to become unacceptable when 327 Heavy Users were active
Figure 4 indicates that the HP ProLiant DL585 G5 server could support 327 Heavy Users before
response times started to increase markedly, validating the optimal value of 288 Heavy Users
derived using % Processor Time values.
