If 0 is generated, the first one will be run (Sampler-10%) If 1 is generated, the second one will be run (Sampler-20%) If 2 is generated, the third one will be run (Sampler-30%) If 3 is generated, the fourth one will be run. 0. You cannot, JMeter waits for previous Sampler response prior to executing next Sampler so if you put all the Samplers under one Thread Group all the requests will be executed at the speed of the slowest request. The Simple controller can be used to make a random request using a link from a previous sampler response, and the While controller with a condition. Let’s see how Jmeter helps us to overcome from the complexity created by other available tools…. Currently it seems to execute a single sampler within a child item regardless of however many there are and then gets randomized again and sent to another child item.
