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?
