Experience Builder Slow Map Layers Widget

[HeatherBell]

We've been building a web app in experience builder. The first page is a map with a sidebar with the map layers widget. When previewing the app, the map loads okay (5-10 seconds), but the map layers widget can take up to a minute to load. I've tried to optimise it by switching off all the layers, and saving the web map using the new map viewer. However, it hasn't sped up the load time. Has anyone found a way to speed up the load time? There are approximately 100 layers in the map but they are all switched off. See the attached image. Thank you, Heather.

Hello Heather,

I am also having the same experiences. I have created first a webmap in the new map viewer and using this webmap to build up in EB. in the map viewer the performance is normal. The performance for popups is also dramatically slow.

Hi Stefan, 

I have raised a case with Esri's technical team who are assiging a subject matter expert. I haven't heard back yet but I will post any solution if there is one on here. 

Best wishes,

Heather

Hello Heather,

Hopefully, they will fix it, otherwise EB is a lose canon. I wondering if you also experiences a slow response with the popups in the map. I think, both are related with each other.

Popup has very slow response in EB compare to new ... - Esri Community

I'm struggling with this issue as well.

Hi All

Was this ever solved / responded to?

Thanks 🙂

I am also wondering the same.  The fact that EB is even slower than WAB and has barely half the widgets make EB useless to us as a web app.  I hope someone has some answers

Is this issue still happening? If so, does anyone care to share a sample app?

Hi, here is a link to our Experience Builder App: https://experience.arcgis.com/experience/9163ff6bdb0f4b34bba59f1a92d9a20f

It is faster than it used to be, by removing some problems layers identified using the Developer Tools in Google Browser, but I would say it is still a bit slow to load.

Thank you, 

Heather.

We are also finding Experience Builder apps incredibly slow to load on SOME computers in our office. It's basically unusable. Our GIS machines load it up fine, but the majority of our staff use shared-pool virtual machines that don't seem to be able to handle the graphics requirements of EB and some of the new Instant Apps. The same map loads up quick for staff when viewed through a Web App Builder apps.
