You use load profiles along with the load type to specify how ReadyAPI Performance should simulate virtual users. This helps you test how your server handles a varying load.
For information on different load simulation strategies, see Testing Scenarios.
To change the selected load profile:
Select the needed load test in the Navigator panel.
Select a load scenario. The scenario inspector will appear on the right.
Select the load profile you need from the drop-down list.

The way in which a load profile works depends on the load type your test is using – VUs or Rate.
As for the VUs load type, load profiles work in the following way:
Profile | Description |
|---|---|
Simulates the specified number of virtual users during the entire test run. | |
Runs a load test with sudden load increases. | |
Runs a load test with the load increase over time. | |
Runs a load test with several load increases and decreases over time. | |
Runs a load test with the number of users simulated according to random value generators. | |
Runs a load test with the number of users simulated according to mathematical waveforms, for example, sine or saw waves. | |
Runs a load test with a custom load shape. |
As for the Rate load type, load profiles work in the following way:
Profile | Description |
|---|---|
Simulates a permanent number of users arriving at the tested server per unit of time. | |
Runs a load test with sudden increases in the speed of virtual user arrival. | |
Runs a load test with the load speed increase over time. | |
Runs a load test with several increases and decreases in the user arrival speed over time. | |
Runs a load test, in which the rate of virtual user arrival changes according to random value generators. | |
Runs a load test, in which the rate of virtual user arrival changes according to mathematical waveforms, for example, sine or saw waves. | |
Runs a load test with user-defined rate changes. |
