Summary: A Mac is 2.3 times slower

I recently ran the following machine code program on both a Mac and a SUN II.

The reason was to evaluate how fast my system would run on the SUN II

start: lea test,a0
	move.l	#100,d0
@1	move.l	#100000,d1		;thats one hundred thousand.
@2	move.l	(a0),d2
	move.l	d2,d2
	subq.l	#1,d1
	bne.s	@2
	subq.l	#1,d0
	bne.s	@1
	rts				;end of test

I got a performance ratio of 2.3 (the SUN is faster) when I ran this test 
and the mouse was completely quite.  The ratio went up to 2.4 when I moved the
mouse around whilst the test was running on the Mac.

The ratio comes from counting ticks on the mac, and system time ticks on the
SUN.
