If the open-folder animation is slow then MacOS hasn't got
the calibration of the DEC/TB register right.

It doesn't have anything to do with actual graphics performance.

There shouldn't be a difference; at least not with respect to
the open-folder animatons etc.

Harmless.

Good.

This might actually be the cause of the timer calibration problem.
Normally, MOL copies a few properties from the hardware device tree
to the device tree presented to MacOS (CPU frequency, bus frequency
and the timebase frequency). You could try altering these
properties in /usr/share/mol/0.9.66/oftrees/oftree.nw. I'm not
sure if these properties are really used though. MacOS normally
performs a calibration of its own.

Do you see a

	'Fixing timer calibration (some frequency)'

line in to log? Also, what is the timebase frequency according
to MOL?
