Instalé una computadora de escritorio después de nueve meses en el ático. De alguna manera dudo que esto esté relacionado, pero no recuerdo que haya sido así.
Tomó aproximadamente seis minutos para iniciar, un par de minutos más para que apareciera la pantalla de inicio de sesión de la GUI y un par de minutos más para que apareciera el administrador de escritorio.
hdparm dio el siguiente resultado:
# 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
Luego ejecuté fstrim así:
# fstrim -a -v
/home: 23.4 GiB (25130262528 bytes) trimmed
/boot: 397.1 MiB (416373760 bytes) trimmed
/: 5.2 GiB (5628624896 bytes) trimmed
hdparm mejoró un poco:
# 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
salida inteligente:
# smartctl -i -A /dev/sda
