Linux Tip: Tune your system for faster performanceLifehacker

Swappiness.pngThe Webs Best explains how you can tweak your Linux system for better performance. The tutorial includes several performance tweaks, but one particularly useful and easy tip is to reduce your “swappiness.” Swappiness is the variable that determines when your system stops using internal memory and switches to using the hard disk as virtual memory, similar to the page file concept in Windows. Since your hard disk is considerably slower than internal RAM, reducing your swappiness and forcing your system to use internal RAM can result in considerable performance increases.

You can reduce your swappiness from the terminal with one command.

sudo sysctl -w vm.swappiness=10

The command shown above is not a permanent fix. However, if you are satisfied with the performance boost, The Webs Best explains how you can make it permanent and do a whole lot more. Although the guide is written with an Ubuntu slant, you can perform these tasks on just about every distro.
