Swappiness is the kernel parameter that defines how much (and how often) your Linux kernel will copy RAM contents to swap. This parameter's default value is “60” and it can take anything from “0” to “100”. The higher the value of the swappiness parameter, the more aggressively your kernel will swap. How to change it? The swappiness parameter value is stored in a simple configuration text file located in /proc/sys/vm and is named “swappiness”. If you navigate there through the file manager, you will be able to locate the file and open it to check your system's swappiness. You can also check it or change it through the terminal (which is faster) by typing the following command: “sudo sysctl vm.swappiness=10” or whatever else between “0” and “100” instead of the value “10” that I used. To ensure that the swappiness value was correctly changed to the desired one, you simply type: “cat /proc/sys/vm/swappiness” on the terminal again and the active value will be outputted
