huh, is this a problem people really have? I just have a plugin that lets me type before zsh loads and I don't really have a problem with this, even before that i didn't really notice a problem since my 'default' configuration is .12s.
time zsh -i -c exit
zsh -i -c exit 0.12s user 0.09s system 81% cpu 0.276 total

# Enable Powerlevel10k instant prompt. Should stay close to the top of ~/.zshrc.
# Initialization code that may require console input (password prompts, [y/n]
# confirmations, etc.) must go above this block; everything else may go below.
if [[ -r "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh" ]]; then
source "${XDG_CACHE_HOME:-$HOME/.cache}/p10k-instant-prompt-${(%):-%n}.zsh"
