GMSMapView Energy Impact

Question

I'm currently using a GMSMapView in my swift app, and the energy impact is never decreasing ( as the CPU usage or Memory usage ).

Did anyone already faced this issue ?

I Found the answer myself. It is related to GMSMarker.tracksViewChanges property.

Turning it to false for all added markers has released the CPU.

Make false of GMSMarker()'s object property tracksViewChanges & tracksInfoWindowChanges

let placeMarker = GMSMarker()
placeMarker.tracksViewChanges = false
placeMarker.tracksInfoWindowChanges = false

It will bringdown energy impact clock indictor.

I was already using tracksViewChanges property but now added tracksInfoWindowChanges as false, and that is showing significant improvement. – prabhu Apr 13 '20 at 11:17

I found google maps to consume to much memory as well. Changing tracksViewChanges worked for me as well.

Another approach that I have tried when the rendering was taking to long, is to split the rendering of the markers or views in the map.

You can use the delegate methods of GMSMapView

to know when the render has finished and add new elements.
