I've never understood how LR can measure or calculate "hits per second". "Hits" implies something has reached its target. I believe the documentation claims it is when a request departs MDRV or the NIC. This is not the same as a hit, in my opinion. An outbound request is not the same as a received request at the SUT side.
If the definition of "hits per second" is as the documentation describes, perhaps the name of the metric needs changing to reflect that it is "requests per second".
