I usually ride to the gravel on pavement(50/50 mix), and wanted to see what a wide road tire would be like while saving my 40mm Clement Xplors for when a local trail (old, closed gravel road) finally reopens from flood damage. I swapped on a set of 32mm Continental Ultra Sport II's and it is no faster, though the cornering on pavement feels much more secure with no tread and they felt faster. Probably going to swap back and go tubeless since the Ultra Sports pretty much give up all puncture protection to be cheap and relatively fast.
