Well, it is your opinion but Rust can be as fast or faster than C, you just need to know what you are doing, if you know every trick of C and try to compare to Rust it is clear what will happen but because Rust it is a more complex lang it can perform better code optimizations, dont blame the tool if you cant achieve the same performance, to really get performance you need to know the https://doc.rust-lang.org/nomicon/ and beyond, the free book it is fine for an entry point, dont expect to become an expert only with it

Another point is that you may want to compile the C code with clang, so that you will compare both with the same backend. (there's an experimental GCC backend for the Rust compiler but it isn't usable yet)

  Safe, fast, small crypto using Rust (by briansmith)

For working software, literally no one is arguing this. For buggy, error prone important libraries written in C, like OpenSSL, yeah, maybe we should consider rewriting incrementally in a memory safe language, like Rust. See: https://github.com/briansmith/ring
