Rust did quite well (given that it's not even production ready i'd say it's impressive): https://mail.mozilla.org/pipermail/rust-dev/2013-September/0...
The only thing they noted was that the Go version "cheated" by precomptuing some values which someone removed to make the algorithms the same.. maybe kid0m4n can comment on this :)
I would argue that it is not cheating "anymore" as both the Go and C++ version are now equal. In fact, I wanna compare how Rust performs in this exact same test with all optimizations applied. Studying those optimizations will be fun itself.
I have also explained why optimizations are perfectly fine (IMHO) here:
https://github.com/kid0m4n/rays#why-optimize-the-base-algori...
I understand that now when the C and Go version we can't compare with the rust version anymore uless someone applies the same changes.. anyway, t was a very interesting read on the rust ML and frankly i was surprised to see rust fare so well
But, I guess algorithmic advances will happen much less frequently compared to other micro optimizations. And it will keep things interesting across the board.
I'm occupied by other things now so won't do it myself, but people are free to work from my code.
