Canary time
Figures 4 shows sample results for an HP ProLiant BL35p server blade running a typical canary script.
Individual user response times are shown in blue, with a yellow line depicting average response
times.
HP analyzed Figure 4 to determine when response times began to increase markedly and consistently
over a baseline level, providing an indication of optimal scalability.
Figure 4: Canary time values – showing an optimal level of 141 Heavy Users
Figure 4 indicates that an HP ProLiant BL35p server blade can support 141 Heavy Users before
response times start to increase significantly, validating the value of 123 Heavy Users derived
using % Processor Time.
