The community member published a headless WordPress site, but it is loading slowly. The comments suggest several possible reasons, such as fetching unnecessary data, loading too much data, and having too many requests. The community members recommend checking the API endpoint, inspecting the network tab, removing unnecessary resources, and reducing the number of requests. However, there is no explicitly marked answer in the comments.
also open inspect and see how much data you are loading, if not sure dump it into a file or open network tab and see if you are not loading hundreds of kilobytes or megabytes accidentally
It is freaking slow https://gogreenhaulerzwa.com/. It breaks the purpose of converting it to headless to improve speed and reduce bloated WP plugins, but the site loading time was super slow.
