システム構成:Dell Inspiron N501-Intel Core i3 380M 2.53 GHz、4 GB DDR3 RAM、1 GB AMD RADEON Graphics、500 GB SATA 5400rpm HDD、Ubuntu MATE 15.10(これはおそらくUbuntu Unityよりも軽い)
Windows 7 64ビットでデュアルブートします。
私のシステムは実行中は非常に遅く、Ubuntuを実行しているときはWindowsよりも遅くなります。ビデオは、再生を開始するとすぐに停止します。クリックには1〜2秒かかります。 Ctrl + Alt + TでもGUIをロードしますが、プロンプトが表示されるまでに3〜5秒かかり、入力を開始します。さらに悪いことに、ほとんどの場合(10回のうち8回)、起動しません。 -そのようなパーティションは見つかりませんでした(またはそのようなもの)と表示され、BIOSディスプレイループに進みます。/dev/sda6でfsckを手動で実行する必要がありました。
この場合のボトルネックは何ですか? RAMまたはHDDですか?
返信してください。ありがとう。
