Prop Pitch speeds

I don't want to start a FM discussion as such but I am just curious if there is a particular explanation behind an observation. It may be because the mechanism is different and I would like to know more about it.

The observation is that when I modify prop pitch from 0 to 100% in a Spit it goes considerably faster than in a bf109 which seems to take an eternity to realize the demanded prop pitch angle. And I am quite sure it is not only the rpm needle but indeed the rpm that changes very considerably slower judging from the engine sound.

Was the mechanism behind the 109 so much different than that of the spit? I would really like to learn about this from an engineering point of view.

EDIT: I chose the wrong forum. It should have gone to the general discussion area. Now I cannot change it.
