The Once Only Logic Controller tells JMeter to process the controller(s) inside it only once, and pass over any requests under it during further iterations through the test plan. Total Requests (12) = Thread Group loop count (2) * Loop Controller loop count (2) * Number of Requests inside Loop Container. 2. In this example, these thread groups are named “First Thread Group” and “Second Thread Group. These controllers can either be placed in Thread Group or in Workbench. This is also can be done using loop controller. Interleave Controller will select only one sampler/requests.
