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! :-)
