How can I increase or decrease swap on my server?
Increasing swap is a fairly simple operation and does not require a reboot. to change
the values simply open the "/etc/sysctl.conf" file and adjust the parameter "vm.swappiness":
Please note $value must be replaced with an integer number from 0 to 100.
0 = No swap would be active.
100 = Swap would be heavily used any values above 20 are not recommended.
