Reduce your Linux memory footprint


IBM software engineer Martyn Honeyford has a paper up on developerWorks that getting some notice over at Digg.com because it teaches users how to reduce the memory footprint of Linux.

A much-touted benefit of Linux is that it is more efficient than Microsoft Windows, and will therefore perform better on less than cutting-edge hardware. This performance makes Linux a very attractive upgrade for the many people who have old Windows 98-era boxes still sitting around that are no longer being treated to the latest and greatest software.

The truth of the matter, however, is that while the Linux kernel can still be configured to be reasonably small and efficient, as new computers have increased in power, many Linux desktop environments (such as KDE and GNOME) have added lots of features. Consequently, the default install of most distributions offer a less than stellar level of performance when installed on older hardware. The same is true of many modern applications also — Web browsers such as Firefox and office suites such as OpenOffice are fully featured, but trying to run them on a machine with 128MB of RAM can be a painful experience!

Never fear: as those in the Linux community have known for years, a great strength (some would say the great strength) of the Linux kernel and Linux distributions in general lies in their ability to be customized. This article delves into how you can tailor your Linux systems for better performance on modest hardware.

An interesting read for all you tweakers out there, which I assume is all of you. You are reading a Linux blog, after all, right?

UPDATE: On second glance this is more for personal boxes, rather than servers. A good read none-the-less however.
