    Use swap less and speed up Ubuntu?

    I have Ubuntu 12.04.

    Can I do this to speed things up?

    Use swap less frequently. It will enable faster switching between applications:

    sudo sysctl vm.swappiness=10

    And edit /etc/sysctl.conf and add the line at the end of the file to set it automatically at boot time:

    vm.swappiness=10

    Thanks.

    That's what I thought.

    If the desktop manager response is too slow, then change desktop managers. Try Linux Mint Mate 64-bit with a Live DVD and see if the response is any better.

    I agree with the others, if you are not using swap, then changing swapiness is not going to have any effect.
