The Inter-Thread Communication plugin offers global string queues for inter-thread communication. These queues work in First-In-First-Out manner. Using a PostProcessor, you can put a string value into a queue from one thread, and then get that value from another thread using a PreProcessor, even in another Thread Group. This allows you to have separate Thread Groups with some synchronization and parameter passing between them. There may be any number of FIFOs, and they differ by "queue name".

For more information, please view the Inter-Thread Communication plugin page.

The Throughput Shaping Timer plugin is used to define your script in Requests Per Second (RPS) over time instead of virtual users over time. You define your steps in starting RPS, ending RPS, and the duration of the step. The first step must start at greater than zero, and the last step must end at zero. You calculate the number of threads needed by multiplying the maximum RPS in your steps by the average response time of your requests in seconds. E.g., for an RPS maximum of 1000 and an average response time of 1.5 seconds, you would need about 1500 threads.
