I don't know what is taking the Mac so long!  Our system, running at 10MHz
with wait states due to memory management, ran the following code in 10.6
seconds.

	main()
	{
		register i;
		double j;

		for (i=10000; i>0; i--)
			j += (1.0 / i);
		printf("result = %9.6f\n", j);
	}

The result I got was 9.787606.

A 68020 running at 12.5MHZ with a 16-bit memory bus ran it in 6.3 seconds.

A 68020 running at 16.667MHz with 32-bit memory bus ran it in 2.8 seconds.
