I have a test case which has 24 samples and the following configuration: Threads : 10 Ramp up period: 60 Iterations: 100 I need frequency =20/hr. My calculation : The entire test case (24 samples) needs to finish every 3 minutes in order to have 20 times per hour. So each sample needs 7.5 sec to execute. Based on this, I should set "Target throughput (in samples per minute)" = 3.0. But "Based on my testing with 1 thread, I need to set the "Target throughput (in samples per minute)" = 8.0 in order to obtain 3 minutes to finish that test? In my configuration, I need to have 10 threads,what should I set for the "Target throughput (in samples per minute)" if I set "Calculate Throughput based on" = this thread only? if I set "Calculate Throughput based on" = all active threads in current thread group ?
