see figures below and take into account that more hash tables doesn't
only mean faster but more accurate search.

with Fritz's automatic test

I used the same settings.

Here's my results, I tested Fritz both with reasonable (i.e. 98304KB)
and "unreasonable" :-))) (12288KB) hash tables. Hiarcs seems mostly
insensitive to hash tables beyond 12MB (compare solution times on AMD K6
with 12MB vs. P5MMX with 98 MB - no noteable performance improvement for
the P5 on longer pondering times despite bigger hash tables).

Summary: The Pentium MMX is only roughly 95% as fast for Hiarcs 6 on
this test suite than the K6 at the same clock speed.

Fritz runs 1.5 times faster on the MMX, additional hash tables give it
another boost (almost as fast as a hypothetical AMD K6 400 :-)).

P.S.: Hiarcs 6 finds FIN 04 on my machine both with 12288 and 98304 KB
hash tables. Albert, could you verify your result for FIN 04 ???
