for the bash case, the cost of forking to write two chars is overwhelming compared to anything related to I/O.

Echo and printf are shell built-ins in bash[0]. Does it have to fork to execute them?

You could probably answer this by replacing printf with /bin/echo and comparing the results. I'm not in front of a Linux box, or I'd try.

There's no forking and it's wrinting one character.
