try fundamental-mode

I tried that, but it is only effective when making small
changes i.e. deleting a character. On my test on a
8612 KB size file, Emacs is not quick enough yet. The
sed command

   sed 's/[A-Z]/0/g' test

needs 17s to finish its job, and vim command

   :1,$:s/[A-Z]/0/g

needs 1min 7s, but even 20min is still not enough for
the Emacs command (in fundamental-mode)

   (replace-regexp "[A-Z]" "0" nil nil nil)

Besides, Emacs uses about 128MB memory. And when
I tried to mark all text, Emacs complains about the
memory.

So I think it is better of using tools such as sed and
vim to edit file bigger than 5MB instead of Emacs,
since Emacs is not good at this job.
