for the mac2, these numbers harden the very rough timing for

	time cat /usr/dict/words > /dev/null

(~200K bytes in four CPU seconds) done on an beta a/ux a year ago.  it
looks almost entirely due to the speed of the system5 vs. bsd4.2 filesystem.
considering how much other bsd stuff apple picked up,
why they didn't go for the berkeley filesystem is beyond me ...
