If so, then why does the speed decrease with more hash? >WP the reason is you are getting close to your maximum limit, i have 256 mb of ram, if i run my chess program at 128, its fine, using shredder, if i use 192, it slows down, and I mean really slows down, from 300 kn/sec to about 45 kn/sec if you had 1 GB of ram, you wouldn't even notice a diff.
