Eu configurei um computador de mesa depois de nove meses no sótão. De alguma forma duvido que isso esteja relacionado, mas não me lembro de ser assim.
Demorou cerca de seis minutos para iniciar, mais alguns minutos para que a tela de login da GUI aparecesse e mais alguns minutos para o gerente da área de trabalho mostrar.
hdparm deu a seguinte saída:
# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 2 MB in 3.75 seconds = 545.64 kB/sec
Timing buffered disk reads: 2 MB in 4.45 seconds = 459.91 kB/sec
Eu então executei o fstrim assim:
# fstrim -a -v
/home: 23.4 GiB (25130262528 bytes) trimmed
/boot: 397.1 MiB (416373760 bytes) trimmed
/: 5.2 GiB (5628624896 bytes) trimmed
O hdparm melhorou um pouco:
# hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 23604 MB in 2.00 seconds = 11811.48 MB/sec
Timing buffered disk reads: 54 MB in 4.27 seconds = 12.65 MB/sec
saída smartctl:
# smartctl -i -A /dev/sda
