Попытка запустить инвентаризационный запрос с внешним соединением - этот запрос занимает больше времени

Ниже приведен мой запрос для получения предметов инвентаризации и количества.Количество напрямую берется из таблицы общих покупок, вычитаемой из таблицы общих продаж на основе идентификатора товара.

Это выполнение занимает больше времени, чтобы ответить и показать данные о DATAGRIDVIEW кода VB.Net.Мой вопрос, можем ли мы оптимизировать скорость выполнения, чтобы ускорить выполнение.

Мой код VB.net для получения данных с сервера: 

            da.SelectCommand = cmd
            dt.Clear()
            da.Fill(dt)
            DataGridView1.DataSource = dt
            con.Close()
