Performance Metrics

Analyze Test Configuration:

IOzone 3.465

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

OpenBenchmarking.org metrics for this test profile configuration based on 1,287 public results since 28 June 2017 with the latest data as of 26 April 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.
