When you run a schedule on the cloud, the location of the data center and the type of host used for agent virtual machines affects the measurement of response time. For example, if you run the schedule on agent virtual machines that use shared hypervisors, other guest operating systems would also be consuming hardware resources. This action might affect the measurement of response time. To avoid such an issue, you can use the Run a Fixed Delay Measurement Audit on every location option. This option applies a fixed time delay on the schedule run. After the schedule run completes, you can measure the length of the schedule run with the applied delay to ensure response time accuracy. If the delay is more, it implies that the agent virtual machines are overloaded.
To verify the response time accuracy of the schedule, you can also run a sample number of virtual users on a control agent that is at another location. After the run, you can compare reports to verify response time accuracy.
