Holy Cow! Sleep may not be working, but my Geekbench score has gone from 12,400 to the following:
MacPro3,1
Section Description Score Geekbench Score
Geekbench 2.3.4 Tryout for Mac OS X x86 (32-bit)

Floating Point Processor floating point performance 22646

Stream Memory bandwidth performance 8331
Could this be because speed stepping is activated. I used to be able to count 2.5 rotations of the "spinning gears" on startup, now there are none because it starts up so quickly! I am puzzled and pleased. No sleep but speedier!
