For our last benchmark, we load all existing products via the GET /products route. Because this causes a lot of loads, we reduce the number of threads in our JMeter configuration from 10 to 2 and only use 50 iterations.

Please note that we now have requests per minute (R/M) instead of requests per second as before.

As you can see, the difference in system load is way smaller this time. While it is still 25%, a load of 4 versus 5 on a machine like the test machine makes almost no difference. However, the pure service is again faster (about 25%).
