Performance Metrics

Analyze Test Configuration:

IOzone 3.465

Record Size: 4Kb - File Size: 512MB - Disk Test: Write Performance

OpenBenchmarking.org metrics for this test profile configuration based on 2,142 public results since 28 June 2017 with the latest data as of 4 June 2021.

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 (IOzone 3.465 - Record Size: 4Kb - File Size: 512MB - Disk Test: Write Performance) 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 4.4%.
