That's the basic conclusion which has been reached over the years each time
this has come up.

I don't recall anyone making measurements, however, and an important rule of
performance is that what one *thinks* about performance is wrong; what one
*measures* about performance may be right--if the thinking that led to the
instrumentation was reasonably close to right.

(Simulation can also do the job if well crafted; NCR Hawthorne's (later
Rancho Bernardo) simulation group in the 1960s and 70s was remarkably
adept--using Simscript.)
