I must admit that I am not sure I quite understood your message.

I noticed that Emacs is noticeably slow when indenting a large C file
(~20,000 lines). It takes more than a second before Emacs responds to
TAB (whether font-lock is on or off).

Also, it appears that c-indent-region is no faster than hitting TAB
several times.
