Disable adjusting CPU performance settings
- Hanno Mueller
This article describes how to change the default InSpec Classic behavior regarding the Windows power mode change.
This procedure is only required if your PC experiences any heat related issues while InSpec Classic is open.
Otherwise, this change will not provide any benefits.
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 adjusts the Windows Power Mode to “Best Performance” which causes the CPU frequency to be at the maximum on most computers.
This allows for improved InSpec Classic performance and avoids potential loss of measurement data due to CPU 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 used, to disable the change of the performance settings when InSpec Classic is started.
Please note that disabling this feature could lead to performance-related issues and applying this switch needs to be evaluated on a PC-by-PC basis.
By default, if “Disable CPU Idle” is not mentioned in the machine.ini, this feature is active (Disable CPU Idl=1), which causes the Windows power mode to be changed on InSpec Classic launch.
To deactivate the feature and prevent InSpec Classic from changing the Windows power mode, add the following switch to the machine.ini file:
Disable CPU Idle=0Restart the PC after changing this setting.
