I have been watching all this intently and wondering if I should switch
from Xenix 2.3.3 to SCO UNIX, just for the disk speed. My 486 is not
out of gas on CPU, but disk access is limiting us. The 486-25 is generic.
The disk controller is Consensys Powerstore, 4Meg Cache on Controller,
ESDI Drives, CDC WREN V model 94196-766 (670Meg), & Fujitsu M2263E (687Meg).
I got 12.5 & 11.1 Sec. Real Time. One drive is faster than the other,
but I don't know which. I repeated several times. CPU time is about 8 sec.
