In my latest binaries, the default libblas.dll is an openblas built for
maximum 2 threads and with dynamic-architecture (cpu architecture is
detected upon initialization and respective logic is selected).
If your cpu has 4 cores, you can try switching to a similar openblas
(dynamic-architecture) built for maximum 4 threads. It may almost double the
performance.
See Octave3.6.1_gcc4.6.2_libblas_readme.txt inside the 7z archive and use
the respective dll file (c.)
