Hello, For those who were weary of my Ruby wmiirc[1]'s power consumption, I am happy to announce that the latest Ruby 1.9.3-p0 stable release has solved Ruby's problem of causing excessive CPU wakeups-from-idle which would drain your laptop battery much sooner than you'd expect.
On my ASUS UL30A-A2 laptop running Arch Linux, powertop[2] shows that Ruby 1.9.3-p0 causes around 2 CPU wakeups-from-idle per second. Top causes for wakeups: 28.8% ( 47.0) [hda_intel] <interrupt> 14.6% ( 23.9) [kernel scheduler] Load balancing tick 11.9% ( 19.4) [ath9k] <interrupt> 11.8% ( 19.3) kworker/0:0 8.0% ( 13.1) [kernel core] hrtimer_start (tick_sched_timer) 6.1% ( 10.0) kworker/u:3 3.1% ( 5.0) syndaemon 2.8% ( 4.6) [acpi] <interrupt> 2.5% ( 4.0) [kernel core] usb_hcd_poll_rh_status (rh_timer_func) 1.5% ( 2.5) wmii 1.3% ( 2.1) liferea 1.2% ( 2.0) kworker/u:2 1.2% ( 1.9) ruby 1.0% ( 1.7) X 0.7% ( 1.2) ario 0.6% ( 1.0) [kernel core] tpt_trig_timer (tpt_trig_timer) 0.6% ( 1.0) ntpd 0.3% ( 0.5) [ahci] <interrupt> 0.3% ( 0.5) watchdog/0 So leave your power woes behind and enjoy wmii with Ruby today! :-) [1]: https://github.com/sunaku/wmiirc#readme [2]: http://www.lesswatts.org/projects/powertop/ -- I have often regretted my speech, never my silence. -- Publilius Syrus
