Infact Gandalf's node count on 500 mhz is on the money with 50 kn/s jr6 300 Kn/s
but on 1.2 ghz it is running at 400-500 Kn/s!! and junior 6 1000-1100 Kn/s
So i get your point now :-) The increase of Gandalf(with more knowledge)
is greater(compared to the 500mhz) than JR6 on faster hardware interesting.
It goes from a 6th to almost 50% of jr6 search abilities.
