Configuração do sistema : Dell Inspiron N5010 - Intel Core i3 380M 2,53 GHz, 4 GB de RAM DDR3, 1 GB de gráficos AMD RADEON, HD de 500 GB SATA 5400rpm, Ubuntu MATE 15.10 ( isto é supostamente mais leve que o Ubuntu Unity )
Eu dual boot com o Windows 7 de 64 bits.
Meu sistema é extremamente lento durante a execução, mais ainda durante a execução do Ubuntu do que o Windows. Vídeos ficam presos no momento em que começam a tocar. Os cliques levam um ou dois segundos para responder. Mesmo CTRL + ALT + T carrega a GUI, mas o aviso leva uns 3-5 segundos para aparecer para eu começar a digitar. O pior é que na maioria das vezes (8 vezes fora de 10), ele não inicializa. Apenas diz - Nenhuma partição encontrada ( ou algo assim ) e, em seguida, entra em um loop de exibição do BIOS. Eu tive que executar fsck manualmente em / dev / sda6 mais vezes do que eu posso contar.
Qual parece ser o gargalo nesse caso? É a RAM ou o HDD?
Por favor responda. Obrigado.
