Public bug reported: Binary package hint: xfce4-systemload-plugin
Ubuntu has set the goal for mobile devices to last longer on a single battery charge. This can be done by several things, of which keeping the amount of wakening the processor to a minimum. Tickless-kernels was a great move forward and now they advice to have around 50 interrupts per second for a fully but idle desktop. xfce4-systemload-plugin 1:0.4.2-1ubuntu3, which has been released for hardy and intrepid, did 4 interrupts per second. This gives the user every 250 milliseconds an update of the systems load. This is a reasonable value for something that has to present non-crucial and more or less real-time info. xfce4-systemload-plugin 1:0.4.2-3ubuntu1, which has been released for karmic and lucid, is doing 12 interrupts per second. This makes it almost the second top-cause for wakening the processor after the kernels function itself. It also takes as much as a quarter of the "allowed" 50 interrupts. Giving this non-crucial info every 85 milliseconds is not reasonable since the user will not gain any informative info. If you program gets stuck and your processor goes up to 100% load, you'll notice this in the same way on a 250 millisecond update as on a 85 millisecond update. I think this is just unnecessary usage of processor- cycles and power. Possible solutions: 1) Set the value back to a 4Hz update, like it has been. 2) Provide a simple option to let the user chose the update frequency, like already done in the xfce4-sensors-plugin. ** Affects: xfce4-systemload-plugin Importance: Undecided Status: New ** Affects: xfce4-systemload-plugin (Ubuntu) Importance: Undecided Status: New ** Also affects: xfce4-systemload-plugin Importance: Undecided Status: New ** Summary changed: - Wakes processor why to often than needed + Wakes processor way to often than needed -- Wakes processor way to often than needed https://bugs.launchpad.net/bugs/506884 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
