  • Disabling this prop can improve performance for custom markers (which is what a cluster is). It would only need to be enabled if the custom marker would dynamically change, which is not the case for clusters.

P-4143 Performance Issue with Map Component on Android.

This issue seems to due to custom marker images and a lot of markers being rendered on the map.

Initial Investigation:

  • Tried reducing the size of marker images, but it's still lagging on Android.

  • Verified by removing the custom marker images,  works well

This is impacting the final delivery of an expert app, so I am keeping it as a high priority.
