Core-Latency

This is a test of core-latency, which measures the latency between all core combinations on the system processor(s). Reported is the average latency.

Learn more about this test at the upstream project site: http://github.com/ajakubek/core-latency.

This utility test profile is maintained by Michael Larabel. This OpenBenchmarking.org test profile was created on 14 June 2019. To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark core-latency.

This test has an average install time of 16 seconds and an average run-time of 18 minutes.

OpenBenchmarking.org metrics for this test profile configuration based on 311 public samples since 14 June 2019 with the latest data as of 15 October 2020.

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 (Core-Latency - Average Latency Between CPU Cores) has an average run-time of 5 minutes. By default this test profile is set to run at least 1 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.
