Hi there,
Thanks for getting in touch about this.
When a page is loaded, Independent Analytics makes one REST API request to your site to record the view. The query that writes the view to the database only takes a few milliseconds. The 1.2 second delay is how long it’s taking for WordPress to load. Anything you can do to speed up your site, such as removing uneeded plugins will help with this.
It’s also important to note that this request is deferred until the page is fully loaded. For this reason, it does not impact the loading experience for visitors, nor does it impact your Core Web Vitals. You can still achieve a perfect 100/100 Google PageSpeed score.
