spending time mostly on exp() calls on an array, other than that a dot product and a sum... openblas I only mentioned because it uninstalled openblas-threads while uninstalling julia 0.5 (by dnf dependency in fedora) and while installing again, openblas-threads did not get installed as dependency. I don't know how exactly this might affect runtime as I'm not sure how openblas is deployed in the background, especially if you are not calling base.LinAlg.BLAS functions explicitly...
