I don't have a clue here. I assume you are using the 13.10 source code
from my ftp machine? If so, this is *exactly* what we played with for
all
10 rounds.
We did use more hash tables than you, I believe our machine had 256M of
memory
and we used 192M for hash. That machine was also at least 2.5X faster
than yours, but you let it search far longer than we could, so that
shouldn't
matter.
I will try this on my machine as well, but perhaps we did have some sort
of
bug that was unknown...
