We can see that when the option to include timers etc is selected the response time of the Transaction Controller includes the 500-millisecond delays between each sampler and when it is not selected it does not. If we run our test now we will see that the ForEach Controller runs for 10 iterations as this is the number of entries we extract from the Return JSON sampler and each iteration contains the value of the response entry. There are a couple of other options the ForEach Controller offers and these are the ability to start and end at a particular point in the array, if you wanted to exclude the first and last record from the array you would set your controller to look like this.
