I found another scenario of excessive equality tests in displaying
text. It can be observed with scrolling the Chinese-BIG5 tutorial: it
is much more sluggish than scrolling the Japanese tutorial, for
example.
I suspect something is wrong in the following part in fontset.c:
581 if (INTEGERP (RFONT_DEF_FACE (elt))
582 && XINT (AREF (elt, 1)) < 0)
583 /* We couldn't open this font last time. */
584 continue;
where AREF (elt, 1) means RFONT_DEF_FONT_DEF (elt).
