Slow query in REGISTER VC_MAP SHORTCODES

Hello,
I have a situation when site speed going slow down.
It happens here: milo-bibo-core/includes/shortcodes/shortcodes.php:282

$args = array(
                        'posts_per_page' => -1,
                        'post_type'      => 'product',
                        'post_status'    => 'publish'
                    );
                    $list_product = array();
                    $post_array   = get_posts($args);

Admin page loads by 14.27S
Using 117,746KB memoory
and 57 query to DB
For now i have

// REGISTER VC_MAP SHORTCODES
                /* A. WOOCOMMERCE SHORTCODE */
                $product_cat = array();
                if (class_exists('WooCommerce')) {
return;

Cuz then it is 1.17S 66,130KB 35Q
But i think this part can get some optimisation.
I have 244 products
