Case insensitve tab completion zsh without increasing startup time significantly

performancezsh

So I wanted to get away from oh-my-zsh because it made my shell startup lag noticeably (>0.1s). Indeed, after removing oh-my-zsh the startup time went to 0.02s but now I started adding features manually back in. First and foremost, the case insensitive tab completion. For this reason I added something like

autoload -U compinit
compinit
zstyle ':completion:*' matcher-list 'm:{[:lower:]}={[:upper:]}'

to my .zshrc. However, this one small feature alone increased my startuptime almost threefold, whereas other feature like syntax highlighting or autosuggestions don't seem to impact the startup time at all.

In bash I can get the desired case insensitive completion simply via
bind 'set completion-ignore-case on' without any performance decrease (startup time ~ 0.01s).

I have no idea what compinit does, but is there no way to get case insensitive completion in zsh without slowing down startup significantly?

Just use Powerlevel10k's instant prompt feature and you'll be able to add whatever you like to your .zshrc without slowing down your startup time.
