Is this not a bit of an exaggeration? I think I saw several comments/issues where people where getting better performance with vectorized code, mostly due to how particular packages are implemented. I think one case was with Distributions.jl, maybe in relation with Turing.jl, but I can’t find it again. Another came up recently here: Speed of vectorized vs for-loops using Zygote - #3 by ChrisRackauckas .
