C. Speed:

It is of course desirable to generate the random numbers fast. While for some applications the generation of the random numbers is the limiting factor, many generators take only a few clock cycles to deliver a new number so that usually the generation of random numbers is only a small fraction of the time required for the calculation. Hence speed is not a major concern unless, either the generator is extremely slow, or the remainder of the algorithm is extremely fast such as with a lattice spin model.
