I agree with you. I noticed the same thing. Q-saves are not that quick. What puzzles me is it's considerably longer in DKS. Once you make it to FoV, the save times are quite shorter and reasonable. I just went and looked at my save files. I'm in the middle of DKS right now (yeah, for the umpteenth time) and they're around 2.6 meg, whereas my saves just before the endgame of FoV are around 1.6 megs. It must have been saving the whole world which is larger in DKS than in FoV.
