cgf который по умолчанию, так там ваще.... заметные тормоза мыли на глаз,
сидишь в ssh сессии, и видно, в какой-то момент системы замирает... т.е.
удаленая стороно не отвечает в ссесию... в это время делаешь новую ссесию -
тоже все глухо... а пинги ходят на ура. (т.е. ядро и сетевая подсистема
видимо реагируют. а то что надо с дисковой подсситемы получить .....)
какие еще шедулеры можно безбоязно попробовать?
а по какие криетриям видно, что запись происходит ооооччччееенннььь медлено?
