less for the data-cache- but even then the cache will have an
effect regardless of strategy.

and the I-cache will do have an effect regardless.

Unless the code in the search algorithm is sequentialy without any
branch/jump (hence everything is only executed once)- maybe
out-of-order strategie of z196 will find bits to do ahead of time.
