Ouch! Couldn't you use a benchmark that doesn't take several days to run? :-)

You don't say whether these are read or write; I get quite different
figures for the two on some machines. Anyway, for your edification:

Machine			Read B/W	Write B/W

PPro 166		85 MB/s		33 MB/s
75 MHz SS20		60 MB/s		42 MB/s
500 MHz 21164*		143 MB/s	129 MB/s	(Interleaved memory.)
300 MHz AMD K6-II**	250 MB/s	100 MB/s	(100 MHz SDRAM.)

I find it a bit odd that the PWS-433A has considerably faster memory
than a PC164. Or is the PWS-433A using a different sort of memory
subsystem?
