[sisyphus] Тормоза при работе с дисками после обновления

["Alexander Borovsky" <alex.borovsky@gmail.com>]

после обновления до сизифа примерно от 20 июля с сизифа от декабря
2005 начала тормозить работа с дисками: при установке пакетов
происходит задержка в пару секунд, postgresql восстанавливается из
дампа > 10 минут (на notebook с тем же sisyphus восстановление дампа <
10 секунд)

Кто виноват и что делать?
