Large Map Pin collection performance issues

[faheys]

Has anyone successfully loaded a large number of Pins via the Map control's ItemSource property?

When the Pin collection is greater than a few hundred items there is a very noticible UI freeze while the pins are being rendered. Seems to take exponentially longer as the size of the Pin collection increases. For example the app freezes for nearly 1 minute with 2000 Pins.

I managed to workaround this issue by loading in the pin data within the view model constructor. This is almost instant when building in realease mode however it is not ideal for cases where large numbers of pins need to be dynamically loaded in.

@faheys which maui maps are you using?

I'm using this nuget:

I'm using the inbuilt Map control which uses Apple Maps on iOS and Google Maps on Android. My app is only targeting iOS for now though so can't speak on whether the issue exists on Android.
I might look into doing some testing with the package you linked and see if it has better performance. Have you had any issues with performance using it?

I'm using this nuget, not the built in one...... Google maps on both ios and android.
