Has anyone else experienced reduced performance in existing MapViewer maps since the recent February 2024 update?  Maps which had a lot of layers on but overall performed fine prior to the update, are now resulting in very slow speeds to load and render.

Hi Joe,

I'm sorry to hear that you are facing performance issues recently! Would you be able to provide a bit more detail regarding it?

  • Are you seeing performance issues across both Map Viewers?
  • How many layers/how complex is the data held within the web maps in question?
  • Are performance issues experienced in any new web maps that you create?
  • Can you test creating a new web map with the same layers as your existing one to see if the same performance issues are seen?

Hi Shane,

 

  • Only tested on the new map viewer - if I open in classic would i lose the group layers?
  • Many. Could be 200 layers
  • Not on new small ones
  • Will report back than on that. I dont want to manually recreate the map though for obvious reasons.

thanks

joe

Are you able to share the map? If you cant share it publicly you can invite russell_jsapi to a group and I can check it out.

What I have noticed is that since the update I am not seeing all objects that should be there in a certain web map, after opening it. After using the zoom buttons (+/-) everything seems to be ok again. Looks like there is some problem building a fresh cache. These are layers from map services from ArcGIS Enterprise.
