Heres a simplified view of what I want Aggregate Thread Group -Txn A throughput controller 20% --txn A HTTP Request -Txn B throughput controller 80% --txn B HTTP Request I want A to be run ~20% of the time, and B to be run ~80%. I dont want the system to have all threads run A, then all Threads run B- I want them to be random, yet work out to the percentages specified. What is a good practice for this? Im unsure if having a parent Random Controller will help (and Im further confused by the difference between Random Controller and Random Order Controller). Thansk, Bruce
