Because the Linux operating systems is more customizable than the traditional operating system, users can run Linux on computers that have limited resources. Many of Linux’s user interfaces and programs are design to be lightweight and can help your system performance. With the correct interface and software choices, you can make an older computer run well. For instance, here’s look at programs that you can choose that will reduce CPU usage.
Graphical User Interface
Determine which window managers are currently installed by booting the computer, go to the login screen and then go to the “session” menu to look at your options. From here, select a user interface that is very lightweight, such as LXXDE, Openbox or Fluxbox. Continue logging in and you should notice the lighter interface that is reducing your system resource usage.
Look at your installed software — browsers and word processors, in particular. OpenOffice and Firefox are considered system resource hogs. Try Chrome or Opera as a Firefox option. Abiword is a very good word processing option to replace Open Office and gnumeric is a great piece of software for spreadsheets.
You can also consider using a simple text editor instead of a full-fledged work processor. A text editor can be just as efficient as a regular word process, while using less system resources.
Finally, monitor your system resources by using the “htop” command from within the command shell to give you system monitor. You will be able to examine which software and programs are consuming the most system resources.
