You are comparing apples and oranges. Apples = NPS, oranges = time to reach a specific search depth. Larger hash tables will slightly lower NPS for some programs. But it will speed up time-to-ply, until the hash becomes too large. At that point, no further improvement will be seen, but larger won't hurt at all unless you go so large you cause paging.
