For example, some presentations at the EasyBuild meetup. There are slides with not so nice figures, e.g., p45 of [1] about FFTW. I remember similar number in other easybuild presentation. In the Guix FFTW package definition, there is a comment about AVX. Well, is it still accurate ? Is Guix binary still slower than other ?
