Are you sure the Mojo code hasn't been optimized? It seems to be hand-tuned with simd operations and multi-threading.

I cannot edit my comment, but you're completely right about it being optimised. I will say that I'm not familiar with what idioms might the Mojo compiler be able to optimise better (a problem arising with the Mojo compiler still being closed source, in comparison with the open source nature of Julia), and, in this sense, I don't know if there is more "compiler friendly" code with the same semantics for Mojo that might allow it to get nearer to Julia results.

The Mojo code here is from the official docs [1], so it's from the people best placed to know what the most "compiler friendly" code for Mojo would be, and what idioms they should use to get the best performance Mojo can provide.

Thanks for the link! Then I guess there is not a lot more that can be said currently, except that maybe Mojo still needs more compiler work. Still, I prefer how readable is the Julia code. :)
