Unfortunately, Bytes/Second would only be applicable for the specific
hardware/firmware combination being tested.  There is such a
difference between disk controllers (DMA vs CPU, clock speeds, etc.)
disk drives, the BDOS and BIOS being run, etc.  That two machines of
supposedly the same configuration can be quite different.  So, what
your looking for is the comparisons for the different programs done on
the SAME MACHINE, preferably near in time.  This can best be expressed
as in index number, with perhaps PIP being arbitrarily set to the
index of 100.  Then, each program would have to be tested against PIP
on the same hardware/software configuration.  Tests done on two
different machines would almost be worthless.  Also, the same program
may behave differently depending upon the hardware, so if your
particular setup has, for example, a DMA disk controller, you may be
better off with a program that takes advantage of the controller, even
if the index number is higher than a different program that doesn't.

In other words, this is a VERY subjective test.
