Saya telah kembali menggunakan Ubuntu lagi, tetapi saya mengalami masalah nyata dengan kinerja keseluruhan Ubuntu 19.04. Ini sangat lamban, terkunci, tetapi yang terburuk adalah itu bisa memakan waktu sekitar 5 menit untuk boot.
Saya memiliki Dell Optiplex 7010 tua dengan prosesor i3 3000 dengan ram 8 GB dan menggunakan grafis onboard Intel HD 3000. Jadi kinerja seharusnya tidak menjadi masalah.
Seperti yang saya sebutkan saya masih baru di Ubuntu, jadi saya masih belajar.
Setelah mencari perbaikan, saya menemukan perintah ini untuk melihat apa yang mengambil begitu banyak waktu untuk mem-boot Ubuntu:
systemd-analyze blame
Yang memberi saya hasil ini:

Seperti yang Anda lihat ada sesuatu yang tidak beres. Saya akan menghargai jika seseorang dapat membantu saya memperbaikinya.
Ubuntu 19.04 adalah pemasangan yang relatif baru. Tapi saya bisa bilang saya punya masalah kinerja dari instalasi bersih. Saya harap seseorang dapat membantu saya memperbaiki ini. Saya menantikan untuk belajar bagaimana melakukannya.
