Update of bug #51871 (project octave): Status: None => Confirmed Summary: load ascii-based numeric file is significantly slow => loading '-ascii' format files is slow _______________________________________________________ Follow-up Comment #4: Just to give an idea of what is possible, I created the large variable 'a' and saved it both in an ascii file and in Octave's own text format with save ('-text', 'odat.txt', 'a'); Benchmarking the read shows that ASCII files load ~4X slower than even regular text files. tic; b = load ('dat.txt'); toc Elapsed time is 4.86173 seconds. clear b tic; b = load ('odat.txt'); toc Elapsed time is 1.13398 seconds. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?51871> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
