Performance Metrics

Analyze Test Configuration:

IOR 3.2.1

Write Test

OpenBenchmarking.org metrics for this test profile configuration based on 455 public samples since 11 October 2019 with the latest data as of 29 October 2020.

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 (IOR 3.2.1 - Write Test) 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.
