Power Plans

BenchmarkDotNet forces Windows OS to execute on the High-Performance power plan. You can disable this feature by modify PowerPlanMode property. You can see it in the BenchmarkDotNet.Samples.IntroPowerPlan.

Please note. During an execution, BenchmarkDotNet saves the current power plan and applies it according to the PowerPlanMode property. When all of the benchmarks finish, a previous power plan comes back. However, if someone killed process or energy was plugged off, we could stay with the High-Performance power plan. In this situation, we should return it manually in Windows Control Panel or by powercfg command.
