The Workload domain covers all aspects related to the generation, execution and monitoring of the workload, with some important tasks like identify key scenarios, determine variability among representative users and how to simulate that variability, define test data, and establish metrics to be collected.
Consolidate this information into one or more models of system usage to be implemented, executed, and analyzed.

Some relevant information, such as the number of virtual users and the delay between user actions, should be considered in the workload modeling.
However, the system flow and throughput are directly affected by the processing time, which can be variable as the workload increases.
