I've tested on a FreeBSD 10 system, with Emacs compiled according to the
emacs-26.2 git tag. Also not reproducible.

Maybe you have some global init files which make the difference? Try

--8<---------------cut here---------------start------------->8---
emacs -Q --eval "(global-auto-revert-mode 1)"
--8<---------------cut here---------------end--------------->8---

'top' for emacs starts with 5% cpu, and decreases then.

On that FreeBSD 10 system, I cannot run X applications (it is a limited
virtual machine). So you could also try in order to have my config


--8<---------------cut here---------------start------------->8---
emacs -Q -nw --eval "(global-auto-revert-mode 1)"
--8<---------------cut here---------------end--------------->8---

Best regards, Michael.
