Question: 

How to limit CPU usage by a service and make it persist across reboots.

Answer:

Solution 1: 

Use the ‘systemctl set-property’ command. You can set the CPUQuota property within the systemd service unit file or using the command line as follows: 

$ sudo systemctl set-property SERVICE_NAME.service CPUQuota=10% 

NOTE: Replace SERVICE_NAME with the name of your service. 

The above command will set the CPUQuota property for the specified service and restrict its CPU usage to 10%. The configuration will persist across reboots because it is applied to the systemd service unit file.
