Based on OpenBenchmarking.org data, the selected test / test configuration (Schbench 2021-09-09 - Message Threads: 8 - Workers Per Message Thread: 4) has an average run-time of 5 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
