AFAIK, buf_bytepos_to_charpos should take no time on plain-ASCII buffers
because
/* If this buffer has as many characters as bytes,
each character must be one byte.
This takes care of the case where enable-multibyte-characters is nil. */
if (best_above == best_above_byte)
return bytepos;
The recipe of measuring the effects is in
https://list.orgmode.org/orgmode/scedec$2g0$1@ciao.gmane.io/
That email literally provides Elisp code to run in order to measure the
effect.
Best,
Ihor
