Yes.

As it mentions as the top: AXP1700+ (Athlon XP 1700+ (1.47GHz))

calls to search/quiesce.

On my machine other programs also get around the same NPS... e.g Both Crafty and
Yace are in the same ball park.

On a small subset of WAC which I calls WACS, 2.18 gets an average nps of
1035784.4.

Cheers, Tim.
