I think some users are already setting bidi-display-reordering to nil. I
stumbled into this the other day, for example:
You can try and see if setting bidi-display-reordering to nil
improves the speed

Should Emacs support that? Should it be added to its doc string that it could
be dangerous?
Thanks,
