M-: (setq bidi-display-reordering nil) RET

After that, repeat the slow commands, compare with Emacs 23 for the
same buffer.  If turning off bidi-display-reordering makes Emacs as
fast as Emacs 23, it's a bidi problem, if it's still slower than Emacs
23, even if it's faster than with bidi-display-reordering turned on,
then it's probably something else.

If the buffer is saved to a file and then that file visited as a
normal file (e.g., in Fundamental mode), does the OP see a similar
slowdown?  If so, is it possible to post the buffer itself here, or at
least send it to me via private email?
