OK hardware people, here's your chance to shine. :-)
Does the size of a MacII monitor influence the speed of the machine?
(In other words, will a <MacIIcx:Dual Page Display> be slower than
a <MacIIcx, Single Page Display>?) As a related question, does
running multiple monitors degrade the MacII's performance?
If I remember right, on the Mac+ the machine spent about 15-20% of
it's time maintaining the video (during which, the processor would
run VBLs, etc.); This, of course, left only 80-85% of the processor's
time available for running applications.
I assume that on the MacII most of the video logic (VRAM refresh, etc.)
has been moved to the video boards, so the processor need not be as
involved in the maintence of the video image. But just how much of the
processor's time is available to application programs? And, if monitor
size effects performance, what kind of performance difference is there
between a TwoPageDisplay system and a OnePageDisplay system?
Please respond via email. I promise to summarize.
+Norm
