Performance Metrics

Analyze Test Configuration:

Intel Memory Latency Checker

Test: Peak Injection Bandwidth - All Reads

OpenBenchmarking.org metrics for this test profile configuration based on 523 public results since 22 April 2021 with the latest data as of 20 May 2022.

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 (Intel Memory Latency Checker - Test: Peak Injection Bandwidth - All Reads) has an average run-time of 2 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.
