Debug zsh startup time

  1. Inject profiling code

    At the beginning of your .zshrc add following: zmodload zsh/zprof

    and at the end add: zprof

    This will load zprof mod and display what your shell was doing durung your initialization.

  2. Measure startup time

    time zsh -i -c exit

And if you forget the command, you may add:

alias zsh_zprof=time ZSH_DEBUGRC=1 zsh -i -c exit

…so you can simply run zsh_zprofwhenever needed.
