This shows clearly the P4 is a step back for chess programs.
Its above numbers are less than twice the speed of my PIII-550 (DS: around 125
Knps, GT: around 120 Knps, Junior around 370 Knps). The T-Bird is much more in
line with what you'd expect from the MHz increase.

This is no miracle since Gandalf is not an SMP program, thus the 240 Knps are
the result for the single 933.
