While the HiarcsMark test is affected by the amount of hash, it will give
misleading results about what is best for playing.  According to a post here
some time back you should give Hiarcs all the memory available without swapping.
 I have run test of over 1500 games and I am sure that even at G/1 min Hiarcs
does better with more memory.
