If we put 5 reqs in it and loop count is 1 then only first req will be executed.

If loop count is two then first 2 reqs will be executed and that too in order.

If loop count is 5 then all 5 reqs will be executed and that too in order.

If loop count is 15 then all 5 reqs will be executed and that too in order and then again all 5 reqs will be executed and again all 5 in order.

Please note if we put thread users to 5 and loop cpunt to 2 then in first loop all five users will hit the same request i.e request 1 in the controller and in second loop all users will again hit the second request and so on .
