Subject: Testing speed of "position visiting"

Here's Peter McKenzie's move generator test position:

r3k2r/p1ppqpb1/bn2pnp1/3PN3/1p2P3/2N2Q1p/PPPBBPPP/R3K2R w KQkq -

There are 193690690 possible 5-ply "games" starting from this position.

How long does it take your program to visit all the positions of these games?

It takes my program 178 seconds. I have a 400MHz Celeron. My code incrementally
updates a 64-bit hash key, a 64-bit pawn hash key, and four material counters
(white pieces, white pawns, black pieces, black pawns).

I'd like to find out if anyone is doing significantly better than this, and
hopefully what methods they're using. :)
