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!
