Recently I’ve noticed that my zsh sessions have become horrendously slow. Here’s how I debugged it.
Measuring Overall Startup Time
time zsh -i -c exit
Finding the Problematic Plugin
Add the line
zmodload zsh/zprof to the top of your
~/.zshrc and at the bottom append the line
This will run and display the costs of running each startup command making it very easy to determine what’s
eating your time. For me it was pyenv, which I promptly disabled to cut my startup time in half.
