CPU clock speed

We are able to understand the cpu current speed and adjust it to the desired speed. Here is how we can do it:

Install cpufrequtils package:
```
sudo apt install cpufrequtils
```
Check the current cpu speed and cpu frequencies:
```
cpufreq-info
```
Check the available governors:
```
cpufreq-info -g
```

tip

If you do not have userspace governor, you will not be able to set the cpu speed specifically.

Change the governor to powersave:
```
sudo cpufreq-set -r -g powersave
```

info

-r: Apply the change to all CPUs -g: Set the governor
