I agree that Experience Builder seems generally slower to load than Web App Builder apps. Initial load is slow and then navigating between pages within ExpBuilder is also noticeably slow.

Hi Susana,

Can you share the experience so we can take a look? If you can't share it publicly, can you share it within a group and add me? My username is dmart.

Thanks,

David

Hello! We are also noticing that the pages/apps made with Experience Builder are very slow in comparing with apps developped in WebAppBuilder. With a map in WebAppBuilder the initial loading time takes 5 seconds. With the same map in Experience Builder the start up takes 30 seconds! Both of the example apps don't have any widgets. Anyone else experiencing that? Where is the problem? Are there any options to speed the initial loading? Thank you for any help! Ana

This continues to be an issue for Experiences we embed in ArcGIS Hub. Sometimes refreshing the page unsticks it, but end users are unlikely to know that, and I would hate to add a note telling them to try that if the map does not load. It seems to do okay if the Experience is loaded into a separate tab.

My Experience Builder project (built with several pages) has the slow load issue and most often it doesn't produce a popup on click or scroll zoom in/out. Different maps respond or don't differently at random. Is Esri making any progress on this? EB is a fabulous idea but simply not usable due to glitchiness... https://experience.arcgis.com/experience/f4b122b0930a4b618d4cb5f35765b2b3/

I am having the same problem where my EXB apps sporadically load very slowly. Sometimes the app will load right away, and sometimes widgets spin for a long time before loading with data. Sometimes but not always refreshing the page helps. Any ideas?

I have 4 pages of an experience embedded in a single host page (generated by another server). The pages are slow to load--sometimes REALLY slow to load i.e. 2 mins. Once the Exp B pages start to load, list widgets whose data is derived from an ArcGIS table take EVEN LONGER. It's sporadic and doesn't seem to depend on local browser caching. Is there anything that can be done? No maps on any of the pages at all. PS Info (wa.gov)

I'm receiving complaints from many in my organization about how sluggish Experience Builder map rendering is compared to Webb App Builder. They're practically demanding to revert back to WAB. Given the deprecation warning ESRI put out back in February and the future of JS3, I'm pushing back and just telling everyone to wait it out, it'll get better. I hope I'm right, but it's frustrating.

A question to those with Experience Builder performance issues - do you corporate PCs have GPUs? Do you have Hardware Acceleration enabled? When an application is built with Experience Builder is running do you see high CPU usage for your browser? What CPU usage do you see here https://registry.khronos.org/webgl/sdk/demos/google/san-angeles/index.html that's an example of webGL that Experience Builder uses.

Our standard PCs have no GPU, so no hardware acceleration, and 100% CPU usage when doing stuff in an Experience site. The same sites work a lot better (still a bit sluggish) on one of our few PCs with any sort of GPU.

I'm not sure what our solution will be, we are just starting the Portal journey, so would want to write stuff in the thing that has longest life, but in our VM world of desktops, we can't just add GPUs without huge expense. Which is why only a few of us will be using ArcGIS Pro.

This is all great when you have organizational control over the hardware, but we are working on an ExB open to the public, compatible with phones and tablets, and the user experience is not great. We have received many complaints about the sluggishness and lag.

I would also state Experience Builder built applications are in general slower than Web App Builder Applications. It is my understanding the underlying JavaScript API is at least partially to blame. We have a developer using 3.x for a web mapping application and wanted to update to 4.x. The 4.x JavaScript API application was much slower and less responsive than his 3.x version.
