Linux Makes For Greener Computing

Posted by Hemos on from the saving-the-earth-and-licensing-fees dept.

An anonymous reader writes "The UK Government reckons that servers with Linux installed are greener than those running Windows. " The reasoning is that Open Source software tends to have lower hardware requirements and requires less frequent hardware upgrades to "keep up with the Joneses"; the Tory shadow chancellor has estimated that the UK could save ~600 million pounds per year by switching to Linux.

  1. More green? Turn on exec mode. by Sobrique · · Score: -1, Troll
    Actually, there's a cool feature in Linux that does actually improve your system performance. It's built into the newer kernels, and is known as 'exec' mode. It's an execution pipeline that more efficiently utilises your system resources. As a fringe benefit though, it also improves performance. It's not a huge impact, only about 10-15%, and is dependant on the application in question. To enable it, all you need to do is add 'exec true' to your /etc/profile.

    Should also work on your user profile, but obviously won't then help for key system processes.
