Per VU Iterations
Control pacing with per‑VU iterations in BrowserStack Load Testing.
Depending on your preferred method, select any one of the following to set per VU iterations:
Set iterations
Select Per VU Iterations from the dropdown menu, and set the number of virtual users, iterations, and the maximum test duration.

- Virtual users: Enter the total number of users to simulate during the test.
- Iterations per VU: Specify the times each virtual user runs the script.
- Max duration: Specify the upper bound on the test runtime (in minutes).
Set iterations
Use iterations to control how many times each virtual user (VU) executes your test script:
- Set
iterations: positive integer per VU. - Combine with
durationif needed: when both are set, the test stops when either the max duration or the per‑VU iterations are reached, whichever comes first.
Prefer loadProfile for ramping scenarios: avoid mixing iterations with staged ramping because it can create ambiguous end conditions.
