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. -- ================================================================================ Mike Bird (These opinions are mine, dammit!)
