It describes the core concept of JMeter in layman’s terms to clear your basics and make a strong platform of performance testing skills using the JMeter tool. You can control the number of users simulated (number of threads), the ramp up time (how long it takes to start all the threads), the number of times to perform the test, and optionally, a start and stop time for the test Sampler: tells JMeter to send requests to a server and wait for a response. 25 minutes. This is kind of weird as it does work and introduces the pause when the thread reaches the sampler. Instead, you use an element of the Constant Throughput Timer, Constant Timer, or Flow Control Action type. If you want to add a delay between each iteration of each thread add a Flow Control Action Sampler as the first sampler and set the delay in the controller.
