@NicolasGIS  as you noted, there isn't a 1:1 relationship between the AMD CDN and a local build of the "@arcgis/core" ES modules. Those use two different module systems, so comparing them side-by-side will always result in different performance profiles. In reviewing the jsapi-custom-worker sample, the network requests and overall performance appear to be working as-designed for "@arcgis/core". I tested the sample locally on my laptop using 4.31, and I didn't see any http request browser stalls. There's definitely a pause when the spatial-join.worker runs, but that's also expected. As I mentioned above, you'll need to use a tool such as Charles debugging proxy to help distinguish between actual http requests and requests are cached by the browser. The chrome developer console tools aren't always telling the full story. Some things you can do on your end to ensure the best performance when building the SDK locally: Host your local build on a CDN If you are hosting the build on your own web server: Make sure your web server is using HTTP/2 If using HTTP/1 set the “Keep-Alive” header ...

@NicolasGIS  please provide a minimal reproducible app so that we can analyze the issue. Here are the guidelines: https://developers.arcgis.com/javascript/latest/troubleshooting/#minimal-reproducible-application. ... View more

Thanks for letting us know @SandroDevos. We've reproduced the issue and are looking into it.  ... View more

@Guy_srb  make sure you have copied the assets from the currently installed version of arcgis/core. The doc provides an example: https://developers.arcgis.com/javascript/latest/get-started-npm/#local-assets ... View more

@NicolasGIS  my recommendation is to open a tech support ticket. That's typically the best route when you have detailed performance concerns. Many (most?) of the cache hits that appear to be duplicates are likely related to the APIs web-workers working in parallel. Also, the browser, itself, is making parallel http requests. Oftentimes, what may seem to be sequential activity isn't necessarily so, and you have to look carefully at the network "Timing" section of the Chrome dev tools, or use a more advanced tool like Charles Debugging Proxy. Initial load time is a multi-factorial issue that includes not just the API modules, but also how the app is constructed, the data, the number and types of layers, the type of queries, how the layers are constructed, etc. I hope that helps. ...

In case it helps with troubleshooting, the SDK's locate widget uses the native Geolocation API under the hood. So, if you can build a simple app for testing with just the Geolocation API, that functionality would be similar to the widget's. ... View more

@AlagappanA  please provide a minimum reproducible app, here are the instructions: https://developers.arcgis.com/javascript/latest/troubleshooting/#minimal-reproducible-application.

@swuell  it sounds like you might be looking for the API's projection engine: https://developers.arcgis.com/javascript/latest/api-reference/esri-geometry-projection.html#project. This functionality can be run on the client, so no need for a server round-trip. ... View more

We recognize that WebGL context lost warnings can be frustrating. Here's some clarification on how WebGL contexts work within the ArcGIS Maps SDK for JavaScript. Hopefully this information helps you with reducing how often they occur. Each MapView or SceneView uses one WebGL2 context. Having too many Views in a browser session is one of the most common causes of these warnings. Generally speaking, adding/removing layers and widgets does not increase or decrease the number of contexts used by the Maps SDK. However, it does affect the amount of resources your app uses, such as memory. The amount of available memory is one of the factors browsers use in determining the maximum WebGL context limit. Please refer to the FAQ on this topic, it contains additional information: https://developers.arcgis.com/javascript/latest/faq/#is-there-a-limit-to-the-number-of-map-and-scene-views-a-user-can-open. ...

The project didn't work, it has configuration issues in Stackblitz and when I tried to run it locally. Also, make sure to include reference to the SDK's CSS.
