Does it prevent the slow-down?

Yes, multi-line constructs will not be fontified correctly.

I am really interested in fixing this without such drawbacks, so if
possible please send an example file.  You can also do this with a
private mail to me if necessary.  If you need something to scramble
the contents you could try something like the following function on a
copy of the file:

(defun TeX-scramble-buffer ()
  (interactive)
  (goto-char (point-min))
  (while (not (eobp))
    (forward-char)
    (cond
     ((looking-at "\\w+")
      (replace-match (make-string (length (match-string 0)) ?x))
      (goto-char (match-end 0)))
     ((looking-at "\\\\")
      (goto-char (TeX-find-macro-end))))))

This will replace any word constituent character outside of macros
with "x".

Copy it into the *scratch* buffer, put point behind the last
parenthesis, type `C-x C-e', change to the buffer to be scrambled and
type `M-x TeX-scramble-buffer RET'.

I don't know how you sent that mail, but it has the disadvantage that
I have to insert the mailing list address by hand when replying.
