Intel Memory Latency Checker Benchmark

Intel Memory Latency Checker (MLC) is a binary-only system memory bandwidth and latency benchmark. If the download fails you may need to manually download the file from https://www.intel.com/content/www/us/en/developer/articles/tool/intelr-memory-latency-checker.html and place it in your PTS download cache. On some systems root privileges are needed to run the MLC tester.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark intel-mlc.

* Uploading of benchmark result data to OpenBenchmarking.org is always optional (opt-in) via the Phoronix Test Suite for users wishing to share their results publicly.
** Data based on those opting to upload their test results to OpenBenchmarking.org and users enabling the opt-in anonymous statistics reporting while running benchmarks from an Internet-connected platform.
Data current as of 31 January 2023.

Performance Metrics

Intel Memory Latency Checker 3.10

Test: Peak Injection Bandwidth - 2:1 Reads-Writes

OpenBenchmarking.org metrics for this test profile configuration based on 40 public results since 17 December 2022 with the latest data as of 24 January 2023.

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.
