MBW 2018-09-08

Test: Memory Copy - Array Size: 128 MiB

OpenBenchmarking.org metrics for this test profile configuration based on 902 public results since 18 September 2018 with the latest data as of 29 September 2024.

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.
