Ran this on an IBM 80, 20MHz '386, 2 megs memory, 110 Meg IBM ESDI
drive, Xenix 2.2.3, and got 1:48.9 real time using the time command.

For comparison on ESIX Unix V.2.D, with a 25 MHz '386, 8megs of memory,
8760E Maxtor ESDI drive with FFS got 0:17.9 real time.
 
I know you didn't ask for the latter but the two machines are about
3 feet apart so I decided, what the heck!

That makes the Xenix on IBM ~91K/sec and the Unix on generic give
about 558K/sec.
