[Octave-bug-tracker] [bug #64975] Octave for Windows extremely slow

[Dmitri A. Sergatskov]

Follow-up Comment #10, bug #64975 (project octave):

As far as I know cputime is approximately tic/toc multiply by number of
threads. tic/toc more like wall time.
E.g.:



$ OMP_NUM_THREADS=16 octave

octave:1> a = randn(5000);
octave:2> tic; inv(a)*a; toc
Elapsed time is 1.6827 seconds.
octave:3> t1= cputime(); inv(a)*a; t2=cputime();
octave:4> t2-t1
ans = 24.022
octave:5> 1.6827*16
ans = 26.923



Dmitri.
