    I have a client and their WP Admin performance is not great, on some page mostly Woocommerce products and settings this is loading very slow in the Chrome network tab, sometimes total page time is 50++ seconds!

    api-fetch.min.js

    What is probably cause this to load so very slowly?

    If you open the Chrome Network you can see this file is being loading many times and every time is like 5 or 10 seconds!

    Slickstack cache did not help improve this or

    Hey,

    This person had similar problems

    https://wordpress.org/support/topic/slowly-process/

    WooCommerce Support team told him probably caused by your WP theme or another plugin that is conflicting with Woo.

    You can try disabling other plugins or change to a different theme?

    Great, however that might just be hiding the problem, if your theme or plugin is poorly coded so might be the actual cause there

    If REST API related you should review this:

    https://stackoverflow.com/questions/49285738/headless-wordpress-rest-api-slow-response-time-javascript

    and test about caching the REST API responses too.

    For future Googlers seems they mentioned this plugin on Stack Overflow for cache the response of REST API

    WP REST Cache

    but yea this might not be related to the cause of slow loading.
