[Octave-bug-tracker] [bug #51871] load ascii-based numeric file is significantly slow

[Dan Sebald]

Follow-up Comment #1, bug #51871 (project octave):

Does

v.push_back(d);

expand the vector size in an efficient way?  E.g., does it grow the available
space incrementally with each new addition to the vector?  Or does it double
the size of available space when there is no more room in the vector?

Worth noting that in your test program the format of the data is assumed to be
valid.  However, the Octave version may be looking at the data file in a more
general sense to ensure that the format for each line has a certain
consistency and sanity about it with respect to previous lines.

Definitely worth speeding up, if possible.  Would make a lot of users happy.
