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.
