Performance Degradation after Upgrading to ArcGIS API for JavaScript 4.29

Question

Hi everyone,

I'm experiencing a significant performance decline in our application after upgrading to ArcGIS API for JavaScript version 4.29 (Map lagging when moving, warning on the console: 'requestAnimationFrame' handler took more than X seconds)

Our application uses a feature layer to load points onto the map, dynamically adding them on the client-side using the attribute source.

To illustrate the issue, I've attached two videos showcasing the performance difference:

* Before Upgrade (v4.28):

* After Upgrade (v4.29.10):

I'd greatly appreciate any insights or suggestions from the community on how to troubleshoot or mitigate this performance issue.

P.S: As far as I am concerned, in this version the improve for the feature layer was improved 😕

Hello @LittleTurtle . Not really, we just refactored a lot of code and it'll help. New versions also look more stable

Hello @LuisSolaRuiz, we are having the same issue with our FeatureLayers, upgrading to the 4.31.6 didn't help.
Where you able to find the issue?

Sure, if you could share the FeatureLayer code that would be great. Also, any additional information about the app would be helpful. For instance, it seems like you have added a GraphicsLayer / sketch experience? How many features are in your feature layer? What renderer are you using? Are you using any feature reduction / clustering? All of this information will help us troubleshoot. Thanks!
