Similar circumstances on an Intel 200 P5 under Win95 last night yielded
1,061,009 fastest and 1,010,105 slowest. More of them ran closer to the
lower mark. Using NT4-Server on the same machine the night before, I
averaged around the 1000k mark but it was running a few services in the

I see no major advantage to running at higher priority when the system is
basically idle. Lots of similar Intels are reporting 50 to 100k less
performance than mine, a few a little better, so I think that the
motherboard may have some effect as well as the processor chip. When my
NT-Server is heavily working, I have seen as little as 786k/sec being

So it would appear that machines and operating systems are relatively
equal, Chip MHz to Chip MHz and O/S to O/S. I have been checking out DES
web page statistics at sites all over the country, and this appears to be
the case. The highest statistics seem to have come from 500 MHz DEC Alphas,
but I haven't seen any statistics from similar Sun and Apple systems (Does
Apple even make a 500 MHz PowerPC?) If nothing else gets accomplished,
this knowledge is worth its weight in gold to MIS depts, deciding on major
equipment purchases.
