FreeBSD 7.2 i386, dual xeon X3230, 4Gb, 2x500Gb SATA2 7200rpm с отключенным AHCI в gmirror round-robin, опции newfs стандартные.
Немного php-скриптов на апаче, через H264 Streaming Module 2 стримится видео.
Размер mp4/flv файлов от 200 до 400 мегабайт и совсем чуть-чуть html-файлов.
К сожалению, не могу добиться скорости отдачи больше150 мегабит - винты загибаются, что мне кажется странным.
Включил поддержку AIO, это добавило порядка 20 мегабит, но все равно к желаемому результату 250+ мегабит не привело.
Что-то не так с настройками nginx? И сможет ли помочь добавление в массив еще 1-2х дисков или замена этих двух дисков на Raptor'ы?
