jmeter Parallel Controller

JMeter Parallel Controller is a feature in JMeter that allows you to run multiple samplers concurrently. It is useful in scenarios where you want to simulate multiple users simultaneously performing different actions on your application.

To add a Parallel Controller to your JMeter test plan, follow these steps:

1. Right-click on the Thread Group where you want to add the Parallel Controller and select "Add > Logic Controller > Parallel Controller".
2. In the Parallel Controller, you can add multiple samplers that you want to run concurrently.
3. You can configure the samplers as per your test scenario and set the number of threads for each sampler.
4. Once you have configured the samplers, you can run the test plan and observe the results.

Note that the Parallel Controller does not guarantee the order in which the samplers will be executed. If you need to maintain a specific order, you can use a Simple Controller to group the samplers in a specific order and then add the Simple Controller to the Parallel Controller.
