Performance Metrics

Analyze Test Configuration:

pmbench

Concurrent Worker Threads: 1 - Read-Write Ratio: 100% Writes

OpenBenchmarking.org metrics for this test profile configuration based on 518 public results since 18 February 2020 with the latest data as of 4 December 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 (pmbench - Concurrent Worker Threads: 1 - Read-Write Ratio: 100% Writes) has an average run-time of 4 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.
