Добрый день. Есть вот такой код. Общий смысл - формируется матрица из товаров, остатков и продаж по ним за определенные интервалы времени. Его выполнение на 700 товарах вешает сервер минут на 15-20. Может быть его можно оптимизировать? Буду благодарен за советы. public function getProducts($sort, $order, $language_id, $quantity_order_total_date_from, $quantity_order_total_date_to, $quantity_order_year_date_from, $quantity_order_year_date_to) { $query = $this->db->query("SELECT p.product_id, p.location, p.quantity, pd.name, pdata.n_price, pdata.n_wt, pdata.coef, m.name AS manufacturer, (SELECT label FROM " .
