quick is for example less than 1000 clocks a node like fritz 5.32/5.16
needed.

quick nowadays is 2000 clocks a node. note that a cpu today can do more
instructions a clock than it could do a few years ago. I don't need to
mention that if fritz got like 900 clocks a node on a P5-133Mhz, that
then needing around 1800 clocks in 2002 on a K7-1.6Ghz means simply that
it is a lot slower now.

How much of that is caused by extra knowledge and how much is caused
by seemingly no longer incrementally generating moves, will probably
remain a mystery.
