Enabling the Performance CPU Governor on System Boot

The set CPU governor are likely to be resetted back on boot. The following steps would ensure that the settings you decide, would stay put across system restarts.

Navigate to
```
/usr/local/bin/
```

Create a shell script file named perf-prof.sh here with the following content.

#!/bin/bash

echo performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

Make the script executable by running the following command
```
sudo chmod 744 /usr/local/bin/perf-prof.sh
```
Navigate to
```
/etc/systemd/system/
```

Create a systemd service file named perf-prof.service here with the following content.

[Unit]
After=network.target

[Service]
ExecStart=/usr/local/bin/perf-prof.sh

[Install]
WantedBy=default.target

Set permissions for the systemd service file by running the following command.
```
sudo chmod 664 /etc/systemd/system/perf-prof.service
```
Reload the systemd daemon by running the following command.
```
sudo systemctl daemon-reload
```

Enable the service which you just created

sudo systemctl enable perf-prof.service

Start the service
```
sudo systemctl start perf-prof.service
```
Check your current CPU governor - if it is performance, you were successfully able to set up the script.
```
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
```

You can use the similar instructions for switching up to any CPU governor of your liking on boot. Just switch the CPU governor name in the shellscript file mentioned in step #2.
