If we want our request to run for a certain amount of time we can use runtime controller.

As an example we make a new thread group and make its loop count to be 1.We then make a runtime controller and put few requests in it and make the controller to run for 15 secs.

So for 15 secs all requests in the controller will run serially i.e when all requests are executed once and if 15 secs and not over then loop will again start even if we didn’t define any loop and then again and again until 15 sec is over.

Now let us change runtime in run time controller to 1sec. So how many of the given requests will run will depend on how many of those are able to run in 1 sec.
