Performance #47

Terminal has felt laggy for over a year. Vim is sluggish. Tmux is slugish. Creating a pane takes 3 seconds because oh-my-zsh (or something) is doing way too much. Investigate why and document findings.

Investigation

• Even paging through git diff is so slow. Lines lag to render when using j/k to move up and down. This is absolutely insane and indicates severe performance degradation at the most fundamental level.
• git diff seems slower in alacrity than iTerm. Wat

Possible solutions

• Reset oh-my-zsh / stop using it?

Long term

• Profile tmux, oh-my-zsh, vim in CI on every push in this repo
