Performance Metrics

Analyze Test Configuration:

IOzone 3.465

Record Size: 64Kb - File Size: 2GB - Disk Test: Read Performance

OpenBenchmarking.org metrics for this test profile configuration based on 205 public results since 9 April 2018 with the latest data as of 19 September 2024.

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: 64Kb - File Size: 2GB - Disk Test: Read Performance) has an average run-time of 3 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 3.4%.
