Argh!

Norton's SI does *NOT* reflect an accurate performance comparison.  It also
depends on which version of SI you use.

For instance, using SI Ver. 3.0, if you take an otherwise stock IBM PC/XT,
replace the 8088 with an NEC V20, and run SI, the reading you will get is
around 1.8.  This wildly exaggerates the 10%-20% speedup one gets with an
NEC V20.

In actual benchmarks (PC Magazine's) pc-ditto was slow in some instances
yet faster in others.  For this reason,  I feel that pc-ditto runs at about
50%-75% the speed of a vanilla IBM PC/XT.
