The value for swappiness ranges from 0 - 100, setting it to 0 swap will not be used, 100 the server will use as much swap as possible.
You can set the swappiness kernel value dynamically using:
Check the current value.
$ sudo sysctl vm.swappiness vm.swappiness = 30
Set new value.
$ sudo sysctl vm.swappiness=35
$ sudo sysctl -w vm.swappiness=35
For permanent changes edit the /etc/sysctl.conf or a file under the /etc/sysctl.d file and change or add
vm.swappiness = 35
After editing the sysctl file run the following, the default file is /etc/sysctl.conf
$ sysctl -p
