Low site performance scores due to enormous network payloads

[thk116]

The top two culprits of this issue are due to shopify assets which I see are being added to the page from a script adding a preloads js file

That script then proceeds to load other scripts from shopify cdn which include the two I mentioned before:

 

These appear to be being preloaded for checkout purposes, which is perhaps not necessary when initially landing on the homepage which is what I'm testing. The first script that loads the other scripts is async, perhaps the async loading is helping minimize the impact but is there a necessity for this?

This doesn't address my question at all

I developed my own theme for my store and I've been noticing this as well.

It's disheartening to learn that all my efforts to optimize page load speeds are made less significant when there are these built-in inefficiencies.

I've looked at the code in these files and they are not necessary on first page load.
