わが国のＩＴはユーザに使用法を十分説明する時間がありません。
このため、初心者がベテランに疑問についてたずねる光景を目にすることがあります。
しかし本来は事故（情報漏えいなど）が発生した場合の責任は、
接続業者、サーバ運営者、システムを開発したエンジニアにあります。
メーカあるいは購入店にたずねるべきです。
利用者の仕事は自治（掲示板の秩序を守ること）です。助言を行ってはなりません。
素人が専門技術に言及するのは「親切」ではありません。「無責任」です。
海外のプロフェッショナルは、「私の仕事ではない」と答えるはずです。

起動はメチャ速くなりました。
要らんモジュールは削ってるけど、それでも速いです。
躊躇せず再起動できます。

まだあまり使い込んでるわけではないので、アレですけど
read は速くて write は期待したほどじゃない感じでしょうか。
tar の展開とか遅いなあって感じが、なんとなく。
ただ、これは気のせいかもしれません。
