Performance Metrics

Analyze Test Configuration:

BenchmarkMutex

Benchmark: Mutex Lock Unlock std::mutex

OpenBenchmarking.org metrics for this test profile configuration based on 431 public results since 1 January 2020 with the latest data as of 22 September 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.
