The CPU Utilization displayed in the Windows Task Manager's Performance tab isn't a direct measure of processing load. Instead, it represents the current CPU speed as a percentage of the maximum possible speed. For example, manually enabling "Best Performance" mode will show 100% CPU utilization, regardless of the actual processing demand. This means that InSpec Classic does not “block” the entire processing load of the CPU when the “Best Performance” mode is enabled. |

By default, InSpec Classic forces adjusts the Windows Power Mode to “Best Performance” which causes the CPU frequency to be at the maximum on most computers.
This is intended to allow maximum allows for improved InSpec Classic performance and avoid the avoids potential loss of measurement data due to reduced clock frequencyCPU power-saving modes.
If the computer is experiencing issues that might be related to this behavior, like excessive heat, the following INI switch can be testedused, to disable the change of the power performance settings when InSpec Classic is started.
