"faster than C" almost always boils down to different designs, implementations, algorithms, etc.

Perhaps it is faster than already-existing implementations, sure, but not "faster than C", and it is odd to make such claims.

I heard that aliasing in C prevents the compiler from optimizing aggressively. I can believe Rust's compiler can optimize more aggressively if there's no aliasing problem.

C has the restrict type qualifier to express non-aliasing, hence it shouldn’t be a fundamental impediment.

> fundamental impediment

This is an interesting word. I wonder why no one has written high performance library code in assembly yet at this point?

Well, most of them is written in C/C++ and Fortran, is it not the case?
