The wc-ajax=get_refreshed_fragments request in WooCommerce is responsible for updating the cart contents dynamically using AJAX. However, it can slow down your website due to frequent requests and high server load.

Disable Cart Fragmentation for Performance

By default, WooCommerce uses wc-ajax=get_refreshed_fragments to update the cart, even when it's not needed.

Disable wc-ajax=get_refreshed_fragments in functions.php

Add this to your theme's functions.php file:

add_action( 'wp_enqueue_scripts', function() {
    if (is_front_page() || is_home()) {
        wp_dequeue_script('wc-cart-fragments');
        wp_deregister_script('wc-cart-fragments');
    }
}, 11);

This removes unnecessary AJAX requests on the homepage, reducing load times.

Disable Cart Fragments on All Pages Except Cart & Checkout

If your site doesn't need cart updates outside the cart and checkout pages, use this:

add_action( 'wp_enqueue_scripts', function() {
    if (!is_cart() && !is_checkout()) {
        wp_dequeue_script('wc-cart-fragments');
        wp_deregister_script('wc-cart-fragments');
    }
}, 11);

This removes cart fragments everywhere except cart & checkout.

Reduce Frequency of AJAX Calls

By default, WooCommerce triggers AJAX on every page load. To reduce this:

Use a Delayed Cart Update

add_filter('woocommerce_cart_hash', function($hash) {
    if (is_front_page() || is_home()) {
        return false;
    }
    return $hash;
});

This prevents unnecessary AJAX calls when the cart hasn't changed.

Cache wc-ajax=get_refreshed_fragments Response

If you cannot disable AJAX requests, you can cache them.

Enable Nginx/Apache Caching for AJAX Requests

For Nginx, add:

location ~* wc-ajax=get_refreshed_fragments {
    expires 30m;
    add_header Cache-Control "public, max-age=1800";
}

For Apache, add to .htaccess:

<IfModule mod_expires.c>
    ExpiresByType application/json "access plus 30 minutes"
</IfModule>

This caches the response, reducing repeated AJAX calls.

Optimize WooCommerce Performance

Enable Object Caching

Use Redis or Memcached for caching WooCommerce sessions:

sudo apt install redis-server

Enable Redis in wp-config.php:

define('WP_CACHE', true);
define('WP_REDIS_HOST', '127.0.0.1');

Use a Performance Plugin

WP Rocket (Recommended)
LiteSpeed Cache (if on LiteSpeed server)
W3 Total Cache (for advanced caching)

Summary of Fixes

Issue	Fix
wc-ajax=get_refreshed_fragments slows down site	Disable on non-cart pages (`wp_dequeue_script`)
High server load from AJAX requests	Cache responses with Nginx/Apache
Too many AJAX requests	Reduce AJAX frequency with `woocommerce_cart_hash` filter
WooCommerce running slow	Use Redis/Memcached caching

Now WooCommerce should load much faster!
