我需要一些帮助来确定为什么我的 shell 速度很慢以及我可以采取哪些措施来修复它。这是一台运行 Ubuntu 22.04 的新机器。不仅启动慢，进入/返回也相当慢。
我尝试注释掉所有添加的插件和自定义配置，但重新启动终端后，我发现没有任何区别。

ZSH_THEME="agnoster"
# Set list of themes to pick from when loading at random
# Setting this variable when ZSH_THEME=random will cause zsh to load

# See https://github.com/ohmyzsh/ohmyzsh/issues/5765

您可以通过注释掉各个行.zshrc并检查它对性能的影响来找出导致 shell 变慢的原因。
nvm并且pyenv速度非常慢。阿格诺斯特的速度相当慢。我不知道gvm是什么。
一旦摆脱了缓慢的东西，启用新插件时请始终注意对性能的影响。如果某些所谓的功能不值得放慢速度，请跳过它或找到更快的替代方案。
