If you click on the link you can see that it takes really long to load up all the points on the map.
I created the same map in google maps to get a performance comparison:
It is way faster than ArcGIS but I am limited to Google Maps which is not acceptable in my case.
I found some ways to achieve better performance:
Clustering! But I couldn't find any documentation on how to cluster in API 4.0 or 4.1 ... just an example in the old API docs (3.18)
Then the next question:
I have to create lines between some of the points (up to 100 connected points in several paths)
Is it still possible to cluster those and disable the clustering at a vertain zoom level?
I hope some of you can help me
