Slow performance and errors on WooCommerce websites are often caused by a large number of AJAX requests, because these requests are not cached. If you run a WooCommerce website and notice a large number of AJAX requests, disabling AJAX Cart Fragments can improve the stability of your website.
About WooCommerce Cart Fragments
WooCommerce “Cart Fragments” is a script that uses admin ajax to update the shopping cart without reloading the page. This feature slows down your website or breaks the caching of pages that do not actually need any shopping cart information.
For example, Cart Fragments on static posts, pages, custom post types and feed pages that contain no eCommerce functionality will reduce cacheability and therefore degrade server performance.
You can detect a website’s Cart Fragments with any web page speed test, or in your website’s Access Log by adding the following to your domain:
https://domain.com/?wc-ajax=get_refreshed_fragmentsCart Fragments will appear in the Access Log as follows:
