Follow-up Comment #14, bug #48085 (project octave): OK. Again I got essentially the same numbers in octave 4.0.2 and 4.1.0: octave:1> lutest_vp2 Simple left division Elapsed time is 1.48758 seconds. LU decomposition c=P*B Elapsed time is 0.0369399 seconds. y=L\c Elapsed time is 0.62088 seconds. x=U\y Elapsed time is 0.619237 seconds. It really looks like the issue with the openblas library. Do you use the same library for all your octave binaries?
