i doubt that the increase from that would make a significant difference on even a set of 1000 images. even given the ideal world that the compiler catches all the optimizations that are possible. after all we are still dealing with data that is more than one generation back - our cameras are not even 16bit.
if you want speed in raw-image processing.. stop waiting for the 64bit "revolution", which wont happen.. work on your settings. use a camera with smaller files. use your camera in circumstances that dont need noise reduction. skip the fancy tools like LCE, ah, better, get rid of all plugins, dont use lens correction etc etc.
or use the ultimate SPEED-UP:
shoot JPG in the final size you need.
