The following position

r3k2r/p1ppqpb1/bn2pnp1/3PN3/1p2P3/2N2Q1p/PPPBBPPP/R3K2R w KQkq - 0 1

has 193690690 leafnodes to depth 5, which took the program 78s, or 2488kns.

2488kns wasn't as bad as I thought it would be, but it's still pretty slow - for example, there is no hashing of the position key here, or any updating of material counters.

Also, the move generation at 12% is less than I thought it would be.

.......

The biggest performance hogger is SqIsAttackedBySide(), correct?


My program shows the same number of perft 5 leaf nodes for that position as yours. It also shows the total number of nodes to be 197,876,242. This would make your moves-per-second number look a little better, as I think it should be based on total nodes rather than just leaf nodes.

My program is also C#, and my IsAttacked routine (presumably roughly equivalent to your SqIsAttacked* routines) shows a slightly smaller percentage than yours. But my move generation percentage is significantly higher than yours, possibly because I'm doing copy-make-restore rather than make-unmake .

I agree with Marco looking at the detailed line timings of a few routines such as SqIsAttacked is the right approach.
