Load Pattern defines how virtual users are instantiated. To configure VU load, select the Load Patten node in the Workflow Tree. There are two ways to create a load: Steady Load and Step Load.
A Steady load is a constant number of users during the entire test. When choosing Steady Load, set the Number of VU property to the number of users you want to create during the test.
Note: The initial number of .NET threads allocated to the StresStimulus process before the test starts is equal to the number of VUs. During the test run, operating system can increase the number of threads if necessary because every VU can issue more than one concurrent request. You can increase the number of threats manually as described in the Load Generator Performance section.
In a step load, the number of VUs increases up to a certain point. The test starts with a Start VU number. Then on every Step Duration, the number of VUs increases by Step VU Increase. Once the Max VU is reached, new VUs will no longer be instantiated.
You can optionally set the Over(s) property to gradually increase the step VUs over a period of time. If Over is zero, then the increase is instant.
Note: The initial number of .NET threads allocated to the StresStimulus process before the the test starts is equal to the maximum number of VUs.
