Based on your data your move generator can calculate only
1,000,000 nodes per second(your program calculates 110,000 nodes per second
based on previous post and 110,000/0.11=1,000,000

I wonder how is it possible that you are faster than Crafty in calculating
perft.

Crafty can do more than 1,000,000 nodes per second when it calculates perft on
your hardware.
