I'm building > the default architecture on macOS, which I imagine is 64 bit. In an unoptimized 32-bit build --with-wide-int: . Without line numbers: 15.9 sec. . With line numbers: 19.7 sec. The times are quite consistent, with jitter of less than 0.1 sec. Note that I don't consider this (i.e. scrolling through a buffer that was already completely font-locked in advance) an important use case for the redisplay purposes, because with today's JIT font-lock this almost never happens.
