Intel Memory Latency Checker

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. Learn more via the OpenBenchmarking.org test page.
