Maybe 10% of the total execution time? Even if bitboards made your move generation 1000% faster, your program would only run 9% faster overall. People don't use bitboards for fast move generation, because bitboards aren't the fastest at move generation (at least on 32-bit hardware). People use bitboards because you can express more complex ideas with them by using a kind of set logic. Whether or not those complex ideas are neccessary is another debate.
