I timed this test on my system with the following results (averaged over
3 runs):

        SCO Xenix 2.3.3    SCO Unix/V 3.2.2

Real:           44.0            14.9
User:            0.0             0.0
Sys:             2.1             6.3

Vitals are: 4MB 25Mhz 386; Maxtor XT-4380E 380MB ESDI drive, 1:1 interleave,
Adaptec controller.  The drive specs claim 18ms avg seek time.

I have both Xenix and Unix installed on this drive -- I'm in the process
of converting over to Unix.  And with these rather illuminating results,
I'm going to hasten my conversion!
