Performance Metrics

Analyze Test Configuration:

Stream 2013-01-17

Type: Copy

OpenBenchmarking.org metrics for this test profile configuration based on 5,493 public results since 31 May 2016 with the latest data as of 3 December 2022.

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 (Stream 2013-01-17 - Type: Copy) has an average run-time of 4 minutes. By default this test profile is set to run at least 5 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 0.4%.
