– Open a terminal
– type in or copy/paste:
sudo gedit /etc/sysctl.conf
– a file will be opened
– add the following line at the bottom of that file:
# Swappiness vm.swappiness = 10 vm.vfs_cache_pressure = 50
– save the file and close it.
After rebooting the swappiness is set to 10. This can be checked by running the following command in a terminal:
sudo cat /proc/sys/vm/swappiness
