Thanks, I haven't had to do dropping to C for a while as the improvement in performance of dotnet along with features like AOT, Span<t> etc close the gap enough for the domain I work in.

Good to know you can remain within the framework and get decent performance though with the unsafe pointers/refs. Would be interesting to see a good benchmark using only C# with latest features and Rust, although I cognisant of the fact there is more to it than pure performance (binary size, dependencies, GC etc).

Rust standard library is far more conservative when it comes to vectorization and auto-vectorization is far more fragile than people think, both links - they beat it in performance significantly ;)
