Decrease the swap use (important)

step1: Check your current swappiness setting:
Menu - Xfce Terminal
Type (use copy/paste to avoid errors):
cat /proc/sys/vm/swappiness
Press Enter.
The result will probably be 60

step2: To change the swappiness into a more sensible setting, type in the terminal (use copy/paste):
sudo -H gedit /etc/sysctl.conf
Press Enter.
Scroll to the bottom of the text file and add your swappiness parameter to override the default. Copy/paste the following two green lines:
(remove space in front of hash)

 # Decrease swap usage to a more reasonable level

vm.swappiness=10

step3: Save and close the text file. Then reboot your computer.
After the reboot, check the new swappiness value:
Menu - Xfce Terminal
Type (use copy/paste):
cat /proc/sys/vm/swappiness
Press Enter.
Now it should be 10.
