Of course.

If it was not important for it than the programmer could ask ssdf and other
testers to test it with 8 MB hash because doing the same result only with
8 MB is more impressive.

I guess that at 60 30 time control on p200(p300 slowed down because of other
jobs may be the same as pentium200) tiger needs half of the hash tables fritz
needs and it is clearly more than 8 MB.

I remember that doubling hash tables make tiger like other programs 7% faster (I
am not sure if 7% is the right number)
