[SciPy-User] Calling scipy blas from cython is slow and non-deterministic

OK, I've made it work.

I was messing the row/column order mapping and the transpose param.

However, it is still slower than cblas.

After having replaced all the cblas_xxx calls in my code (about 8 of them), I
get the following result

cblas version 0.69 sec
scipy blas 0.74 sec

Any clue why?
