Xamarin Forms - map display response time

See original GitHub issue

I am trying to display map with points and path added. After a xamarin forms page is opened with map, it takes almost 30 seconds for page to become responsive, so that you can move around or zoom in/out.

Tried with 2.0.2 and 3.0-rc.1 but seems that there is no difference Any suggestions?

Here are some debug infos from app:

Hi Dino,

from your debug log I read that you work on iOS. (Mapsui runs on a couple of different platforms, so this information is actually quite relevant).

Any experience with similar issues?

Yes, indeed I have also observed performance issues with Mapsui.Forms on iOS, in particular when using many Pins or long Polylines, see e.g. #1084. Performance on Android is significantly better in my experience.

It would be great if one could manage to identify the most severe performance bottlenecks on iOS and get rid of them. Also it would be good to find out why there is such a difference in performance between iOS and Android. I kinda have that one my todo list, and hope to get to it soon (lately I was busy dealing with other issues unfortunately).
