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.
