    Centos7 + Postgresql 9.6 + 1с 8.3. Очень долго входит в базу (до 20 минут). Но если сеанс с этой базой уже установлен, то следующий создается менее, чем за минуту. Сеанс может быть как толстым\тонким клиентом, так и через консоль кластера. Если все сеансы убить через консоль, то первый сеанс снова будет создаваться 20 минут. Подскажите пожалуйста, в чем может быть проблема. Что вообще происходит при создании первого сеанса?

    Да, производилась оптимизация памяти с помощью pgtune

    А асинхронность записи изменений в таблицы включали?
