What is Scaling_governor?
The “scaling_governor” feature enables setting a static frequency to the CPU. When CPU frequency governor is set to “powersave” mode, CPU is set to the lowest static frequency (within the borders of scaling_min_freq and scaling_max_freq).

How do I know if my CPU is throttled?
CPU Throttling – Resource Monitor In the run box, enter: perfmon.exe /res and tap the Enter key. Use your system like you normally do. The Maximum Frequency value shows the current power consumption by the CPU. If the value does not go beyond a certain point, it means the CPU is being throttled.
Is it possible to disable frecuency scaling on Linux?
Most modern CPUs already have really good cpu cooling systems, so this shouldn’t be an issue, however make sure this doesn’t cause a huge extra power consuption or CPU over-heating. As you see, you can disable CPU frecuency scaling easily for both RedHat and Debian based distributions.
How to disable CPU speed scaling on running system?
Here is a tip how to disable it on running system: 1) Check that ‘kondemand’ thread is running, run as root: “pgrep -lf ondemand” the output should be like: 2) Check that current cpu speed differs from the maximum: 3) Change CPU governor from ‘ondemand’ to ‘performance’ for all CPUs/cores, run as root:
What does frecuency scaling do to the CPU?
This CPU frecuency scaing allows a processor to run in less frequency than maximum allowed. This is done only to preserve power consumption, but the downside of this is that you are not able to use your full CPU speed. How can I find at what speed is my CPU running?
How to enable or disable CPU cores in CentOS?
