I promised a posting when we had some good numbers to report if I had
interest expressed; here they are:
Controller 386/ix(1.06) SCO SV/386 CORETEST (DOS)
---------- ------ ---------- ---------
WD1003-WA2 85KB/sec 100KB/sec 153KB/sec (1:3)
WD1003-RA2 90KB/sec 105KB/sec 210KB/sec (1:3)
ACB2372A -- Unknown -- 112KB/sec 670KB/sec (1:1)
WD1006-V/SR2 235KB/sec 348KB/sec 680KB/sec (1:1)
(KB = Kilobytes, not bits)
All tests conducted in single-user mode with no daemons active using:
time dd if=/dev/rhdxxx of=/dev/null bs=32k
Only the wall-clock time was used in the computations, of course.
All measurements were made over at least a 20 Meg partition to reduce error.
I would expect other SV/386 ports to be similar to Interactive (they are
closer brothers than Xenix is).
If we had a reliable installation for 386/ix 2.0 (on the one customer machine
that's using it) we'd have some numbers for that as well....
