Sistema muito lento, tentando encontrar o gargalo

Question

Eu tenho o Ubuntu 12.10 instalado na Sony VIAO E Series VPCEH16EN, 4 GB de RAM, HDD de 320 GB, processador Intel Core i3-2310M 2.10GHz. É uma inicialização dupla com o Windows7 juntamente com ele.

Eu vejo o sistema demorando a responder, qualquer vídeo fica preso entre o jogo. Você pode me ajudar a encontrar onde está o gargalo? Aqui está a saída de hdparm e 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
anil@anil-ubuntu:~$ 
-----------------------------------------

-------------- SMARTCTL -----------------
anil@anil-ubuntu:~$ sudo smartctl -a /dev/sda6

Answer 1

Seu S.M.A.R.T. os dados do seu disco mostram que seu disco rígido está falhando. Gostaria de fazer backup de qualquer informação que você possa ter importante em seu disco e substituí-lo o mais cedo possível.

Todos os avisos Tipo: Pré-reprovação devem ser claros, além do 104, 105, 106, 107 e 108 erros no relatório smartctl .

Você também pode verificar o status das condições do seu disco rígido (mostrar pelos dados S.M.A.R.T.) usando o palimpsest ( Disk Utility ) e verificando o status lá
