Bringing down my ZSH load times from ~3.1s to ~230ms

This year, the amount of time I spend in the terminal has gone significantly up thanks to Claude Code. Couple of things: I have this insane tendency to close tabs as soon as I’m done with them Over the year, my work computer ZSH dotfiles have gotten extremely bloated I got to a point where I couldn’t tolerate how slow opening a new shell session got. Naturally, I decided to fix it. First, I needed to truly understand how slow my zsh was. I ran time to get the exact load time of my zsh. time zsh -il -c exit -i: interactive mode; needed to understand prompts, completions, aliases, etc.-l: login mode; needed to load /etc/zprofile and ~/.zprofile, etc.) in addition to .zshrc (I only use .zshrc and a ~/shell_overrides.sh file to load computer specific config)-c exit: run the exit command immediately and quit These give you a true load time. The result didn’t come as a surprise. 3.1 seconds load time. It’s a ridiculously high number. No wonder I hated opening a new terminal session so much.…
