CPU cores can enter power-saving modes, and the Linux kernel manages that via idle governors. We should investigate whether the choice of the governor affects reliability of benchmarking. If yes, we should make recommendations in our documentation or let BenchExec detect and fix or warn problematic situations.

The kernel documentation for CPU Idle Time Management contains more information.
