Linux Mintの起動と認証は非常に遅いです。

Linux Mintの起動と認証は非常に遅いです。

Linux Mintをインストールしました。ところで始動速度が遅すぎます(20~30秒)。認証中にも3〜5秒かかります。たとえば、Windowsはロードに最大5秒かかります。 (私はSSDを持っていますが、SSDにもミントがインストールされています)

インストール中、ディスクはルートディレクトリとホームディレクトリに分けられます。たぶんこれは問題ですか?

私はIntel CPUとSSDシステムを搭載した古いコンピュータを持っていません。なぜ?

結局のところ、認証中にパスワードが間違っていると非常に速く通知されますが、パスワードが正しい場合はシステムが停止し(オレンジ色が一度点滅します)、5秒後にデスクトップが表示されます。

システム終了時間も長い(15秒以上)
