    • In terminal, type "sudo gedit /etc/init.d/rc" without the quote marks.

    Open your file manager, (Konqueror or Dolphin)
    • Go to the directory /etc/
    • Right click on the file "sysctl.conf"
    • Click Actions --> Edit as root
    • When the text editor opens, scroll down to the bottom of the file.
    • Add this code: vm.swappiness=0
    • Save the file and exit the text editor

    Remove any files you don't need to the Trash Bin

  6. 6
    Reboot.
  7. 7
    Your PC is a bit faster, have fun!

edit Tips

  • If you are not sure what you are doing, consult help before majorly editing important system files. You could have an inoperable system if you wreck it beyond recoverable.
  • Update frequently (Use sudo apt-get update)
  • Keep a virus scanner on your computer, spyware detector, and adblocker. A lot of these types of files are free and open-source for Linux, so enjoy.
  • More tweaks are available at Top 10 Ubuntu Hacks
  • CONCURRENCY=shell runs boot scripts in parallel, which increases performance but has a small chance of uncovering bugs. If this happens, simply revert the change.
  • vm.swappiness=0 reduces paging of memory to disk, which increases interactive performance. You can set this after boot with 'sysctl vm.swappiness=0' as sudo or root user.

edit Warnings

  • Never do this to someone else's computer without their permission.
  • If you wreck your system, or it has been so badly modified that it doesn't work, reinstall it (preferably a different version). If it is recoverable, in boot options, select "Rescue a broken system".
  • Always be sure of what you're doing; it's alright to ask

edit Things You'll Need

  • A computer with ubuntu installed (If you don't have Ubuntu, ask for a free live CD from http://www.ubuntu.com, or just download its ISO and burn it.)
