It is: (1) on a 25 MB file (not the typical case), (2) on a file with an
exotic encoding (not a typical case either). On typical files (UTF-8 or
single byte encoding) the delay is not noticeable (a few milliseconds).

It would be much faster, especially with very long lines, which was the
question with which this bug report started.

Yes, I don't understand why syntax highlighting is used in such buffers,
IMO it's useless, it would be useful only if (1) it were reliable and (2)
all lines were highlighted.
