WordPress 插件减慢网站速度

Question

我开发了一个 WordPress 插件，它在我的本地和其他一些服务器上运行良好。但是很少有客户抱怨我的插件拖慢了他们的网站。有人可以帮我解决这个问题吗？

此代码会降低网站速度吗？

class MyPlugin_WC {
    
        protected $auth;
        protected $admin_settings;
        protected $frontend_actions;
        protected $backend_actions;
        protected $cron_actions;

        public function __construct() {
                $this->load_dependencies();
                $this->define_backend_hooks();
                $this->define_frontend_hooks();
        }
        
        /**
         * Load all required dependencies
         *
         * @return void
         */
        public function load_dependencies() {
            require_once ABSPATH . 'wp-admin/includes/file.php';

            $this->cron_actions     = new MyPlugin_WC_Cron_Actions();
        }
 
        /**

        public function define_backend_hooks() {

       }
       .....
}
