FeatureLayers load very slowly for the first time

Hello!

The version I'm using is 4.26.5.

I used the vue @ArcGIS/croe ES module to create the feature layer and found that it loaded a lot of working files for the first render, which was slow and hindered the rendering of features. It would be much better if the browser was cached later. How can this be solved.

How can I speed up the loading of these workers files, thanks!

be solved.
