I think that 2-3% is not a lot and there are cases when changes that should change nothing about speed may change the speed by more than it thanks to different compiler optimizations. I got bigger slow down when I decided to change the structure of the files by adding a special file for functions that I do not do often like setboard instead of having them in the same file as my move generator. I decided that it is probably not important and only random compiler optimizations. Uri
