I have these plugins: git, zsh-autosuggestions

    /usr/bin/time -f "%e seconds" zsh -i -c exit
    0.06 seconds

This is acceptable, maybe the zsh-autocomplete is the problem for author or something else?

I originally switched to ZSH + Oh My Shell because it opens so fast. Ideally plugins would initialize asynchronously but it's not very easy with shell scripts I think.
