The number of nodes per second is not the important thing.
It is important to know which lines to search.
If complicated rules tell you which lines to search then you may be slower in
node per second but faster in seeing tactics.

Another important thing is the evaluation function.
Programmers could search more nodes per second if the evaluation function was
only counting material but the result in this case is a very weak program.
