In ArcGIS JS API 3.xyz, the feature layers only loads to the current map extent(only a portion of map loads), however, in ArcGIS JS API 4 the full map is loaded upfront which makes the page loading very slow if multiple layers are loaded together.
Note: The problem is only specific to loading the feature layers.
Is there a way we can constraint the map loading to the current extent of the map similar to API 3.xyz?
