I have seen a K6-2-300 outcompile a PII-350... but the idea that one K6-2/400
beats a PAIR of anything in the same class is just what Byron said.  Bogus. 
Essentially it's a timing loop, and it's probably only getting a look at 
one of the two Intels... 

Which leads me to the following related question:  is GNU make(1) smart enough 
to take advantage of SMP?  I remember at GaTech we had a Sequent Symmetry we 
could kick off make -P and snarf all ten processors on the thing.... emacs
compiled in a trice.  One would love to turn a quad-Xeon loose on the kernel
recompile.... can you say, way sub-sixty-seconds?
