Ubuntu's Power Consumption Tested

Posted by kdawson on from the no-lyme-disease dept.

RedDragon writes "Ubuntu 7.10 is due out on Thursday, October 18, and in addition to desktop 3D effects, GNOME 2.20, and other features is the use of the Linux 2.6.22 kernel with the tick-less (CONFIG_NO_HZ) kernel feature. But does this mean enhanced power savings when compared to past Ubuntu releases? Phoronix tested Ubuntu power consumption looking back 2-1/2 years at the six Ubuntu releases from Ubuntu 5.04 to the yet-to-be-released Ubuntu 7.10. Testing was done when the system was idling and then under load, and when the Lenovo notebook was powered via the battery and then again with the AC adapter. The Pentium M CPU temperature was also monitored. While Ubuntu 7.10 does include the tick-less kernel feature, more daemons and processes running by default on these modern Ubuntu releases is actually causing an increase in power consumption."

      The point is to not get modded offtopic. You got modded offtopic, JoshJ. SloshyJoshyJ. JJ. Jay Jay the Jet Plane. John Jay. Jay bird. Hey, lay away the J for a day it'll pay I say. See, I can say whatever I want, and because I'm anonymous, I can be the biggest jackhole in the universe. I can even piss, off grammer Nazi's. And I loose no karma. You did. You got modded offtopic. The parent poster didn't, because of that little box that says Post Anonymously. And because the mods usually aren't smart enough to see if you're replying to a modded down post or being originally offtopic, that probably a good idea.

      Ahhh! A newbie Troll. Most Trolls I know wouldn't bring themselves as low as to explain why and how they're Trolling. They would just look down at the respondee with contempt and laugh at the offtopic mod. And, Mr. Newbie Troll, (note here that I have also pissed off the Grammer Naxi's by starting with 'And' without caring or being AC) I have plenty enough karma to modded down many many times, so I have no problem pointing this fun factoid out. So are you so new at this Newbie that you bottom is still red raw from the inaugural Troll spanking rite?

    Err, shouldn't they be comparing it against exactly the same setup without the kernel tick giberish-thingy ?

    On other news, windows 3.11 needed quite less powerful machines than windows vista.
