We have an issue about the VisualizationLayer control fo RadMap, we are currently on version 2016 R3
We try to display +1500 data in a country with smooth performance when moving or zooming, but actually we tried a lot of things and nothing change.
We started to use InformationLayer and it was perfectly smooth but all points were on top of each other and it was ugly.
So we change to VisualizationLayer, while setting ItemsSource + Clustering enabled:
- Dataloading was correct
- Moving was smooth (in same zoom)
- But Zooming in or out was extremely slow and froze everything for some seconds
Then we added GenerateClustersOnZoom = false
It helps a little when its zooming but at the end we have the same freeze as before when it actually refresh all clusters
And let some clusters on the map (I don't know why)
We also tried with a VirtualizationSource, it was a little better but still far from the behavior of the InformationLayer
What do we need to do to have Clustering as fast as the InformationLayer in term of moving/zooming on the map ?
Or why the clustering is so time consuming ?
