That 10% of your code is twice as fast? That doesn't say much for the other 90%. I spend under 10% in move generation, so I haven't spent much time at all tweaking that as it is wasted effort. Yace isn't two times faster, by the way. It seems to be pretty comparable in speed to Crafty. _overall_. Which is the only _important_ measure...
