Greetings, I came across this issue as the layers in my web map kept growing: turning the Layer List widget (LLW) on causes a longer and longer delay between the map.setExtent call and the actual AGS request.
It happens under Web AppBuilder 2.2 and 2.3 with AGS 10.3.1.
Interestingly it does not happen under Web AppBuilder Portal Edition (Portal 10.3.1).
Has anyone had a similar experience and if so can you please share how it was resolved (short of reducing the number of layers in the map)?
Here are all the details.
This is what one zoom call looks like with LLW off.
