Running Windows 95 on a Pentium (I) 166 MHz, with 128 Mb memory; getting the
following (approximate) node per second (nps) speeds:
Software NPS
------------------------------------------- -------
Fritz5 (16 bit) within Chessbase Light 140,000
Crafty v17.14 (alone in dos shell) 25,000
hash/hashp sizes of 48M/10M
Crafty v17.14 within Winboard v4.1.0 25,000
1. Why is Crafty slower? Do the results suggest that I'm doing something wrong
(i.e. correctible)? Are there any (other) tuning parameters (for Crafty within
Winboard or Crafty alone) that I can set to (dramatically) enhance performance?
2. Can hash/hashp sizes be controlled when using Crafty within Winboard (versus
Crafty alone in a dos shell)?
3. I'm thinking of buying Fritz6. For those of you who have experimented with
Fritz6 (32 bit), Fritz5 (16 bit, within Chessbase Light) and Crafty (on the same
hardware), what nps speed should I expect from Fritz6 (based on the nps speeds
charted above)?
4. Any guesses on Fritz7 ETA?
