The speed the bits travel should be negligible in comparison with the time it takes the intermediate(routers, switch,...) and end nodes to receive/process the signal. So if you're curious for computational purposes it wouldn;t matter. Electricty in a vacuum travels at light speed. I'm not sure the effect a copper medium would have. It would probably be less due to interference and other electromagnetic influeneces.
