I've tried to reproduce the problem with the recent Emacs build. I let
cat run for about 6 min; emacs' cpu usage didn't exceed 15% during that
time. The zed file results in

# ls -l zed
-rw-r--r-- 1 albinus albinus 11726983168 Nov  5 22:12 zed

So I cannot confirm your observation, sorry.

Could you pls show exactly your recipe, starting with "emacs -Q"?

Best regards, Michael.
