sudo pico /proc/sys/vm/swappiness
{change 60 to 10, save with [Ctrl] [O] [Enter], exit with [Ctrl] [X]}
cat /proc/sys/vm/swappiness
10
3. Edit /etc/sysctl.conf, and add vm.swappiness=10, vm.vfs_cache_pressure=50 to the end of file
sudo pico /etc/sysctl.conf
{move cursor to the end of file and then add this}
vm.swappiness=10
vm.vfs_cache_pressure=50{Save with [Ctrl] [O] [Enter], exit with [Ctrl] [X]}
