You need to pass -d to zsh to make benchmarks fair. Otherwise zsh is
sourcing global configs while bash doesn't.
time ( repeat 1000 zsh -df -c '' )
time ( repeat 1000 bash -c '' )
I get 4 ms and 3 ms for zsh and bash respectively.
Note that this number has virtually no bearing on interactive shell
startup time.
