The Jetway in the sim connects to my aircraft to fast in my opinion, and should be slower as in real life it takes a couple of minutes for the jetway to connect. However-in the sim takes a few seconds to connect.
There should be an option to customize how fast or slow the jetway connects, such as a slider.
I think there are far too many sliders and options in the Sim, without adding any more, unless it’s really importanti. It should be easy enough to compare the speed of real jetways with those of the Sim, and if the concensus is that the Sim ones are too fast then ask for them to be slowed down. Personally I can see no valid reason why the jetways should not operate at a slower speed, as that really has no effect on the simulation, but if they operated any faster it would clearly look unrealistic.
