Hello,
Try the following code to speed up the loading
add_action('wp_enqueue_scripts', function() {
if ( !is_admin() ) {
wp_deregister_script( 'jquery' );
wp_register_script( 'jquery', "//ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js", false, '1.12.4' );
wp_enqueue_script( 'jquery' );
}
}, 130);
Let me know if it helps.
Regards
