[Marco Biscaro <marcobiscaro2112@xxxxxxxxx>]

As the original bug reporter, I can confirm this bug is now solved *to
me* with Ubuntu 12.04 (unity version 5.14.0-0ubuntu1). When idle, compiz
consumes < 1% of CPU time and when moving windows and doing other things
related to windows management, it consumes about 5%.

Daniel said in comment #197 that "performance bugs are almost always too
vague and subjective" and I agree. My performance problem (which this
bug report represents) is now solved. I'll mark this bug as fixed, and
ask that other people that face similar performance problems that open
another bugs reports with their specific hardware info and steps to
reproduce.

Thank you for your understanding.

  compiz consuming a lot of cpu

Bug description:
  This problem is exclusive to unity (when running compiz with gnome-
  panel, this doesn't happen).

  1. Close all windows opened, if any
  2. Open a terminal and run 'top'
  3. Notice that compiz is consuming a lot of CPU time (although there is nothing special running). In my case, it's consuming about 13% when idle.
  4. Unmaximize the terminal window, if maximized, and start moving the window slowly
  5. Notice that compiz is now consuming much more CPU than before (in my case, arround 50%).
  6. Open a video.
  7. Notice that compiz consume much more CPU than idle (about 25% in my case), although I'm not doing anything related to window management.
  8. (optional) Install the gnome-panel package and choose "GNOME classic" in login screen. Start compiz with "compiz --replace" and follow the steps from 1 to 7. Notice that the CPU consuming is much lower (in my case, 1% when idle, 25% when moving the window and 9% with the video).
