CHUD nap vs Energy Saver Automatic

Both are there to reduce the CPU speed when it is idle, right ?

If CHUD is installed, there is a "nap" setting in the hardware preference pane in System Prefs. How does this differ from the "Automatic" Processor Performance setting in the Enery Saver preference pane ? Both are there to reduce the CPU speed when it is idle, right ?

See http://www.latext.com/pm/comments/807_0_1_0_C/ (especially some of the later comments). Based on that:

  • nap seems to do more than Energy Saver
  • nap can cause system instabilities if you don't use the current version of CHUD and MacOS X
