The Spitfire had hydraulic propeller pitch change system, the 109 (190) an electric, and it was slow from everything I've read, so its correct.

Electric systems tend to be slower than hydraulic ones, but I guess the advantage is that they are less failure prone or sensitive to battle damage (ie. no leaks as in a hydraulic system, less fire risk). The same is true for example for tank turret traverse solutions.
