Performance Metrics
Analyze Test Configuration:MBW 2018-09-08
Test: Memory Copy, Fixed Block Size - Array Size: 128 MiB
OpenBenchmarking.org metrics for this test profile configuration based on 1,298 public results since 18 September 2018 with the latest data as of 8 January 2025.
Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.
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%.
