[Rhythmbox-devel] idle rhythmbox

["Peter Robinson" <pbrobinson gmail com>]

Hi All,

The guys at intel have just released a tool called PowerTop
http://www.linuxpowertop.org (announcement to fedora-devel -
https://www.redhat.com/archives/fedora-devel-list/2007-May/msg00796.html
)

Anyway I installed it to play around with and noticed that rhythmbox
was appearing fairly frequently even though it was idle and not
playing (I forgot I even had it running). Something like 6.2% of the
nearly 2500 wakeups in a second (output below).

Anyway, you may well be aware of it, just thought I'd point out the tool.

   PowerTOP version 1.0       (C) 2007 Intel Corporation
