[Radiance-general] No more Mr. Nice Guy

[Greg Ward]

I completed my tests on my G4 PowerBook, and the difference is even  
greater than with the G5 desktop.  These are the results:

Radiance Speed Comparisons			
	Highest	Automatic	Reduced
G5, nice=0	90.9	91.1	182.2
G5, nice=+6	90.9	166.1	182.4
G4, nice=0	182.8	184.6	366.7
G4, nice=+6	184.3	365.6	367.7

I've plotted this in Excel, spreadsheet attached.  (Write to me at  
<gward at lmi.net> if you want the 268K gif plot.)

The net difference is even more pronounced on the PowerBook -- a full  
factor of two between "nice" and "not nice" in "Automatic" mode.   
Basically, having "nice" and "Automatic" together is the same as  
setting the processor mode to "Reduced" on both platforms.
