Type: Add

OpenBenchmarking.org metrics for this test profile configuration based on 1,912 public results since 31 May 2016 with the latest data as of 8 March 2021.

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.
