On an Everex 3000A (386DX/16MHz) running SCO XENIX 386 2.3.2 with an
Adaptec ACB-2372B RLL Hard/Floppy Controller and a Maxtor XT-1140 MFM
Hard Disk (1:1 int., 28ms, 1024 Cyl., 15 Hds., 26 Sec./Trk., 183MB)
it took 35 seconds. That's approximately 286K per second. The Adaptec
is rated at about 900K/Sec. and utilities like The Power Meter under
DOS reaffirm that fact. That's a big difference in speed between the
two operating systems. BTW, the CPU is rated at 3.4 VAX MIPS has 3MB
of RAM. Is dd really a reliable way of judging transfer rate?
