The cpupower service can adjust the clock speed of supported CPUs based upon
the current processing load thereby conserving power and reducing heat.
The cpupower
service can be disabled with the following command:
$ sudo systemctl mask --now cpupower.service
The cpupower service is only necessary if adjusting the CPU clock speed provides benefit. Traditionally this has included laptops (to enhance battery life), but may also apply to server or desktop environments where conserving power is highly desirable or necessary.
