Система очень медленная, пытаясь найти узкое место
У меня установлена Ubuntu 12.10 в Sony VIAO E Series VPCEH16EN, 4 ГБ ОЗУ, жесткий диск 320 ГБ, процессор Intel Core i3-2310M 2,10 ГГц. Это двойная загрузка с Windows7 вместе с ней.
Я вижу, что система очень медленно реагирует, любое видео застревает между воспроизведением. Не могли бы вы помочь мне найти узкое место? Вот выходные данные hdparm и smartctl:
------------- HDPARM -------------------
anil@anil-ubuntu:~$ sudo hdparm -Tt /dev/sda6
/dev/sda6:
Timing cached reads: 2 MB in 3.51 seconds = 584.17 kB/sec
Timing buffered disk reads: 160 MB in 3.02 seconds = 52.91 MB/sec

Ваш С.М.А.Р.Т. данные с вашего диска показывают, что ваш жесткий диск выходит из строя. Я хотел бы сделать резервную копию любой информации, которая может оказаться важной на вашем диске, и заменить ее как можно скорее.
Все предупреждения типа : перед отказом должны быть ясными, за исключением ошибок 104, 105, 106, 107 и 108 в smartctl отчет.
Вы также можете проверить состояние вашего жесткого диска (показать по данным SMART) с помощью palimpsest (Disk Utility) и проверить состояние там
