I installed all dependencies listed in HACKING.txt (including libblas-dev and liblapck-dev) and built octave develop-source.
should i do something about blas or lapack when I run octave?

For the particular example you showed, the computation speed only depends on the BLAS/LAPACK libraries you are linking to.
What implementation of BLAS/LAPACK are you using?
