Based on OpenBenchmarking.org data, the selected test / test configuration (MBW 2018-09-08 - Test: Memory Copy, Fixed Block Size - Array Size: 128 MiB) has an average run-time of 2 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.

Based on public OpenBenchmarking.org results, the selected test / test configuration has an average standard deviation of 0.8%.
