A Rust-based TLS library outperformed OpenSSL in almost every category
The implication here is that it does better because it's written in rust.  I doubt that's the case.  I think it's faster because it's new, smaller (i.e. doesn't have to deal w/backwards-compatibility with previous versions or old protocols).  More importantly, it uses the ring library for crypto, which is over half asm according to its github.  Clearly, there's a lot of optimization there.Regardless of the reason why, I'm very excited to see a better alternative to openssl.  More competition will hopefully make all the projects better, and I wish the rustls guys the best of luck.
