[Bug 784055] Re: CPU usage increases dramatically (and visible stuttering) when running indicator-multiload

 

For what it worth that argbToRgba code (which I'd like to move to
GdkPixbuf asap) isn't really used in indicator-multiload as it provides
the actual icons to show, so the shell has "only" to paint them, and
unfortunately this is something that looks somewhat slow.

The argbToRgba function is unfortunately a needed thing, but only for
indicators providing pixmaps, that are in such format and we don't have
access to other C code doing this better right now.

Bug description:
  using 0.1-0~5~natty1 on mostly up to date natty system, when running
  the indicator-multiload with with just cpu monitor and the default
  update interval of 500 milliseconds, I see (via top) that compiz usage
  when generally idle goes from either 0 or 1% of CPU to 3 or 4% of CPU.
  Reducing the update interval does seem to have an affect.

  I realize that 
  a.) top is not scientific
  b.) there could be something I'm missing here
  c.) saying "300%" (in the subject) is not scientific
