What is the bottleneck in system выступление?

System Configuration: Делл Инспирон Н5010 - Intel Core i3 380M 2.53 GHz, 4 Великобритания DDR3 ОЗУ, 1 Великобритания AMD RADEON Graphics, 500 Великобритания SATA 5400rpm HDD, ТУСКЛЫЙ Ubuntu 15.10 (this is supposedly lighter than the Убунту Унити)

Двойственный I Windows boot with 7 64 - бит.

My system is extremely slow while running, обитал so while running Windows Ubuntu than. Видео get stuck the moment they start playing. Clicks take в second or two to respond. Even CTRL+ALT+T loads the GUI but the prompt takes в some 3-5 seconds to шоу up for я to start typing. What's worse is that most of the укради (8 укради out of 10), it does not boot. It just says - не such partition found (or something like that) and then goes on в BIOS display loop. I have had to run fsck manually on/dev/sda6 обитал укради than I хан count.

What seems to be the bottleneck in this вступил в брак? Is it the ОЗУ or the HDD?

Please reply. Thanks.

Прекратите использовать тот диск прямо сейчас и:

  1. Купите новый диск, больше и быстрее затем тот, который Вы теперь имеете
  2. Сделайте полный диск - к образу диска от старого диска до нового дискового использования dd или CloneZilla
  3. Удалите nearly-broken-disk из своей машины
  4. Добавьте клон, который Вы просто сделали
  5. Если Вы купили больший диск:
    1. Загрузите Ubuntu LiveDVD
    2. Использовать gparted для расширения старых разделов до размера, Вы теперь хотите, чтобы они были
    3. Засните и позвольте ему работать в течение ночи
    4. Молитесь ангелу жестких дисков и ангелу питания, ничто не идет не так, как надо во время расширения.
  6. Сделайте новое полное резервное копирование своей рабочей системы.

Почему?

Все следующие параметры:

1 Raw_Read_Error_Rate     0x000b   100   100   050    Pre-fail  Always       -       0
3 Spin_Up_Time            0x0027   100   100   001    Pre-fail  Always       -       2012
5 Reallocated_Sector_Ct   0x0033   100   100   050    Pre-fail  Always       -       136

находятся в предварительном сбое, что означает, что в ближайшем будущем, Вы собираетесь быть в реальной проблеме как полный катастрофический отказ жесткого диска.
