나는 다락방에서 9개월을 보낸 후 데스크톱 컴퓨터를 설치했습니다. 이것이 관련이 있는지 의심스럽기는 하지만 이런 식으로 기억되지는 않습니다.
부팅하는 데 6분 정도 걸렸고, GUI 로그인 화면이 나타나는 데 몇 분, 데스크톱 관리자가 표시되는 데 몇 분이 더 걸렸습니다.
hdparm은 다음과 같은 출력을 제공했습니다.
# 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
그런 다음 fstrim을 다음과 같이 실행했습니다.
# fstrim -a -v
/home: 23.4 GiB (25130262528 bytes) trimmed
/boot: 397.1 MiB (416373760 bytes) trimmed
/: 5.2 GiB (5628624896 bytes) trimmed
hdparm이 다소 개선되었습니다.
# 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
smartctl 출력:
