If you want to configure swap, just change the swappiness of your system.
Simply echo a value from 0 to 100 onto /proc/sys/vm/swappiness . The higher a
number set here, the more the system will swap - and the other way round, of
course. You can see the current value of swappiness with the
command "cat /proc/sys/vm/swappiness". Default 60. I use 20.
