I don't know why we are arguing about this. I think its common 
knowledge that X is better and more modern but it also is signficiantly 
less efficient in many ways. If you go look on the box for something 
like Native Instruments plugs or Arturias Moog, you will see the 
requirements when running system 9 to be something like 500 mhz and 733 
mhz if you are running X. That means to run the same plug you need 
almost 50% more processor speed to compensate for the lower efficiency 
of X. I have used several computers over the past few years with both 9 
and X, and although 9 is looking more and more dated, it actually 
reacts faster.

About graphics being redrawn - they are re-drawn much more often than 
you might imagine. If you have several windows open, any time one 
obscures another, and you click on the back on, its redrawn. Anytime 
you click on any window I believe causes it to be redrawn (note the 
grayed out title bar change). Whenever you have things like graphic 
audio meters or knobs or things that move - they must be redrawn each 
time there is any movement. If you turn a knob on a softsynth I think 
each fraction of a turn causes a redraw. If there were not the case, 
then you could not see the pointer for the knob move until you reached 
the stoping point. But you actually see it moving as you turn it. So it 
might cause 50 redraws for that window in a second.


>So yes the fancy graphics make the look&feel slightly slower, but the 
decrese in real computational power
>(which we see in less possible tracks with Logic etc) comes from the 
more complex architecture of OSX.

Ok that might be true. It might be because of the better multi-process 
threading which 9 doesn't have. Actually there are a lot of processes 
going on at any given time in X.

>Switching off all fancy graphic things (which in fact you can) doesn't 
have much influence on that.

How do you do that?
