Have you tried testing the ExportMap operation on each individual service to see if one of them is especially slow?

Both the Search widget in Web AppBuilder and ExB support coordinates in the format X,Y:EPSG code. For example: 2500000,7500000:2953 I was surpised when I learned about this a few months ago. It is in the documentation for the search widget. I believe LKS94 is EPSG 3346: Bernie.

This is a great idea. It will simplify cert management for ArcGIS Enterprise administrators.

@Tyler_Fleming, I'm in a similar situation. We don't use Portal to keep our architecture simple. So we use AGOL to publish our vector tile basemap. All our data is open so we have no security concerns. Bernie.

Many end users expereince poor performance with an ExB app on their old or weak hardware. Even if the ExB app is only using a basic 2D map interface. My idea: Add an option for publishing an "ExB Lite" app. The resulting app would not have the higher hardware requirements of a standard ExB app. The justification: Many apps do not require the additional capabilities provided by WebGL and GPUs. Unfortunately, ExB apps require a GPU, WebGL support, and 8 GB RAM. WAB apps do not require WebGL support and run very well on older computers with low resources and no GPU. Feature Web AppBuilder Experience Builder JS API 3.x 4.x Rendering DOM/Canvas (2D) WebGL (GPU) Depends on GPU Minimal Heavy Browser requirements Lower Higher Typical weak point CPU GPU / VRAM / drivers Compatibility Older browsers fine Needs modern GPU and WebGL support My web traffic shows over 10% of our users are still using our WAB app even though an ExB version of the same app have been available since Decmber 2024. We tried to encourage all users to use the ExB app: We made the ExB version the default app, the WAB app is only avaialble via a new URL. We labelled the WAB app as "Deprecated". I strongly suspect 10% of our users are running older and weaker hardware that cannot support an ExB app. All our apps are available to the Public. We have no control over their hardware choices. Implementation: Perhaps the best implementation might be through some ExB templates that are limited to features that will not require GPU and WebGL2.0 support.

It sounds like you have all the parcel data for California (a google search estimates 13 million parcels in California). Perhaps a Vector tile cache would be a good option. You should be able to refresh the vector tile cache easily when you get updates from the counties. Bernie.

wizgis, I agree with @JoshuaBixby. You should look to optimize your data in ArcGIS Pro. Additionally, you should look into how much load the server is expereincing. Is the RAM or CPU maxed out during times when you see these problems? If not, I would recommend trying to increase the min and max instances. Timeouts could indicate there is not an instance available and requests are waiting too long in a queue. More instances could alleviate the problem. But you should look to optimize your layers as well. How many services have you published? Do you just have the one service with 12 layers? If that is the case I would definitely split your layers across multiple services as suggested by @RPGIS . Bernie.

Here is my understanding of the problem. The ArcGIS JS 4.x API requires WebGL 2.0 support on the end user's hardware. To run WebGL 2.0 efficiently a GPU is required: Older systems that do not have drivers or hardware (GPU) to support WebGL 2.0 will not be able to load an ExB app. Systems that have a driver to support WebGL 2.0 but do not have a GPU will attempt to emulate a GPU with the CPU and perform very, very poorly. Our solution was to publish an ExB app but to also retain our old WAB app to support users with old hardware. We placed several warnings in the WAB app related to deprecated software. Currently, about 9.7% of our users are still using the WAB app. Bernie.

By the way, I have an Acer laptop I purchased for $500 in 2016. It will run ExB apps just fine. It make me wonder - "How long do people wait before they upgrade their computers??"

To help my users understand their problem running ExB apps I have created a test page for WebGL 2.0: WebGL Capability & Performance Test It is a single page web app - HTML, CSS, and JS all in one html file and its only 376 lines. If you would like to use it with your users please copy the source code to your own web server. It's licensed under the "Unlicense". Bernie.

I was very happy to discover the ExB Search widget supports projected coordinate systems. All you have to do is include the EPSG code when you enter the coordinates. It is documented here. When you use this feature, a request is sent to the GeometryServer to transform the coordinates. However, when I examined the web traffic I can see the requested output spatial reference is EPSG 4326: Our basemaps are in EPSG 2953. Why does the Search widget presume I want the output in EPSG 4326? This extra transformation degrades the output accuracy. My Idea - Add configuration options to the Search widget to allow me to: set the preferred output spatial reference, or set the preferred output spatial reference to match the spatial reference of the basemap.

We currently publish all of our ExB apps through AGOL. Is it possible to register and use a custom widget with ExB apps hosted in AGOL?

‎11-25-2025

Thanks @JeffreyThompson2. We currently do not use the Developer Edition of ExB. But I recently heard it is possibl to have a custom widget without deploying the Developer Edition. Have you attempted this?

We have upgraded from WAB to ExB but many users are complaining about the shape of the mouse pointer during measurement operations. I can see why they are complaining. The fat lines in the cross obscure the point you are trying to click on (snapping is not an option): How hard is it to customize the shape of the pointer in the measurement widget? I would prefer something like this: Thanks, Bernie.

@yockee , I have never done any work with WFS but I do have one observation. The URL for the service you are publishing is ...testing_WFS7/MapServer/WFSServer. To make changes to features I think you would have to begin with a feature service - not a map service. It's just a guess. Good luck, Bernie. P.S. I really hope to see you succeed in editing an ArcGIS Server service with QGIS. Have you tried asking this question in a QGIS forum?
