I suspect that the Fritzmark (or Shreddermark, or whatever) is a series of known chess problems, and the resulting number is a measure of how long it takes to solve them as compared with an internal standard of some kind. I have Shredder 7, not Fritz 8, and will give the suggestion of odd/even hash table values a try. I doubt it will make a difference, but you never know. I did a lot of experimenting trying to determine proper hash table sizes and concluded that it's impossible to do. So I just set them for a reasonably big number, while leaving enough free RAM for the op system to be comfortable.
