[Octave-bug-tracker] [bug #51871] loading '-ascii' format files is slow

[Dan Sebald]

Follow-up Comment #44, bug #51871 (project octave):

"With that, I think there isn't too much more inefficiency that can be
squeezed out of this one"

Ah, not exactly.  The


  std::istream::sentry se(is, true);


can be moved outside of the getline_alleol_sanscomment() function and just
called once prior to the do loops scanning every line.  It saves a few
percentage points, time-wise, but that is no longer a drop-in replacement for
getline(), so I didn't include that in the speed-up-load-ascii-v8.patch patch.
