I've wondered that as well.

I seem to recall reading somewhere that a properly trained Welsh or English longbowman could achieve a greater rate of fire than a continental crossbowman or arbalestier(?). I'm not sure if that was comparing against cranequin(?)-style crossbows or ones that used a lever (goat's foot?) to tension.

One difference is that you can aim a crossbow. My understanding is that longbowmen involved their entire bodies in drawing their bows, and so it was difficult to aim. So, they had to make up the difference with greater range and rate of fire.
