On master started with -Q in a buffer containing a single line
consisting of 800 repetitions of "السّلام عليكم Hello " (in the buffer
the string " Hello " was to the left of the Arabic string because I
yanked the latter first), with bidi-display-reordering at its default
value t and with point at point-min, running (benchmark-run nil
(end-of-buffer)) returned:
(5.249231941 1 0.014300497000000023)
After moving point back to point-min and setting bidi-display-reordering
to nil, running (benchmark-run nil (end-of-buffer)) again now returned:
(0.034058467 0 0.0)
