You need a Transaction Controller. the Include Controller loads a simple. When I run the Main. Download and start JMeter. 3 you can use only a single variable in the ForEach Controller. 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. Take advantage of that, saving yourself time and frustration. 2. I find there can be alot of repetition between plans, which often means.
