Swap Memory

There is a swappiness factory, see /proc/sys/vm/swappiness.

Setting it to 0 will turn of swap. The recommended value is 10.

To set this at system start use /etc/sysctl.conf.


To turn swap on and/or off use the commands swapon and swapoff

See https://askubuntu.com/questions/1357/how-to-empty-swap-if-there-is-free-ram

swappiness of 0 will turn off swap completely.
