Is it the last zsh version that's being tested? There was 2x startup
improvement at 5.4 or something like this.

Also, Zplugin can load plugins after prompt, I load 20 plugins, and my
startup times are:

repeat 5 { time /usr/local/bin/zsh-5.6.2-dev-1 -i -c exit }
/usr/local/bin/zsh-5.6.2-dev-1 -i -c exit  0,09s user 0,04s system
117% cpu 0,111 total
/usr/local/bin/zsh-5.6.2-dev-1 -i -c exit  0,10s user 0,05s system
119% cpu 0,130 total
/usr/local/bin/zsh-5.6.2-dev-1 -i -c exit  0,11s user 0,05s system
121% cpu 0,129 total
/usr/local/bin/zsh-5.6.2-dev-1 -i -c exit  0,09s user 0,04s system
115% cpu 0,119 total
/usr/local/bin/zsh-5.6.2-dev-1 -i -c exit  0,09s user 0,04s system
117% cpu 0,109 total

I even load prompt after a default prompt, ~ 100 ms after it. The
Star-Trek console-like impression this gives can be visible here:

background.
