Many, but not all, of the math functions are implemented using the
BLAS/LAPACK libraries. Try installing OpenBLAS for a (multicore)
performance boost over the standard BLAS functions. It is a drop-in
replacement so you should not need to recompile Octave.

Didn't realize switching BLAS colud be done without a recompile for Windows. Grabbing the Win32 or 64 versions of OpenBLAS is simple enough. Is it a straightforward procedure to get it hooked into Octave?
