The U5 certainly isn't a fast machine, given that it's only just about
2x faster on a "build the world" benchmark than my SGI Challenge S with
a R4400@200Mhz (which is quite an old machine).
The U5 replaced an original pentium@100Mhz with a non-UDMA capable IDE
interface (PIIX3 or PIIX4, can't recall which off the top of my head),
and there is a definite difference. With the Intel box, any operations
on some of my big MH folders were a "go get coffee and come back" type
of operation; the U5 isn't lighting-fast, but it is quite snappy enough.
OTOH, if the Intel box were 2x faster than mine and did more than multi-
word DMA, it'd probably beat the U5.
