I don't believe the comparison is proper. Shouldn't be written like this?

~ > time vim -u NONE -c 'q'
vim -u NONE -c 'q'  0.01s user 0.01s system 44% cpu 0.045 total
~ > time command emacs -Q -nw -e 'kill-emacs'
command emacs -Q -nw -e 'kill-emacs'  0.11s user 0.05s system 97% cpu 0.165 total

The idea of startup time comparison is not that meaningful though. And
the best way is just what you have mentioned: keep emacs running on.
