私のシェルが遅い理由とそれを解決するために何ができるのかを理解するのに役立ちます。これはUbuntu 22.04を実行する新しいシステムです。起動が遅くなるだけでなく、エントリー/リターンもかなり遅いです。
追加されたすべてのプラグインとカスタム設定をコメントアウトしようとしましたが、ターミナルを再起動した後に何の違いもありませんでした。

# See https://github.com/ohmyzsh/ohmyzsh/issues/5765
# COMPLETION_WAITING_DOTS="true"
# Uncomment the following line if you want to disable marking untracked files

.zshrc
個々の行をコメントアウトし、パフォーマンスに与える影響を調べて、シェル速度を低下させる原因を見つけることができます。
nvm
そしてpyenv
非常に遅いです。 Agnostはかなり遅いです。私はgvm
それが何であるかわかりません。
遅いものを取り除いた後は、新しいプラグインを有効にしたときのパフォーマンスへの影響を常に認識してください。いくつかのいわゆる機能が速度を遅くする価値がない場合は、スキップするか、より速い代替案を見つけてください。
