Performance Issues on Zoom in and Zoom Out

[JohnLucotch1]

Good Morning,

We are currently working a 2.1 WAB application that has 40+ layers.  We have noticed in the migration from 1x to 2x that the rendering of the layers and basemaps takes a good 30 seconds when zooming in and out.  The slow rendering on zoom in and zoom out is almost non-existent in the 1x version.  Has anyone else had these issues?

John,

  I can not say I noticed.

We ended up replacing the 2x Layer List within the WAB 2.1 with a 1x Layer List and everything started working just fine.

Hi John,

Following up with a thread you posted regarding the LayerList 1.x widget not having zoom performance issues. Would you happen to be able to share the widget for download? We are experiencing some slower performance issues that could be related to the LayerList widget. 

Thank you,

KC
