If you use "new" completion (compinit) then the slowest part is reading and 
parsing all completion functions.

You can speed it up by precompiling; see zcompile and function autoloading in 
Zsh manuals.

I do something like

for i in $fpath; do
  zcompile $i $i/*(N)
done

and wrapper function that checks modification time to automatically recompile 
if needed.

it depends on your rc files actually. Ubuntu ships zero rc files for zsh and 
startup is very fast :)
