Hi

I run the whole WM-Test (100 positions) with 16, 32, 64, 128, 256, 512 and 1024
MB Hash. On MY computer the most solutions (and the fastest one) where reached
at 256 MB, but there where a couple of solutions that where only or faster
solved at 32, 64, 128, 512, 1024 or 64 (It was significantly weaker at 16, I
susspect a lower bound there!). The overall performance was best at 256. Of
course on a faster computer it might be better at 512, who knows? All I proved
with that was that "Shredder is very sensitiv to Hash size settings"

Bye Ingo
