ISRG has been investing heavily in the Rustls TLS library over the past few years. Our goal is to create a library that is both memory safe and a leader in performance.
Back in January of this year we published a post about the start of our performance journey. We've come a long way since then and we're excited to share an update on Rustls performance today.
What is Rustls? Rustls is a memory safe TLS implementation with a focus on performance.
I can’t be bothered to build them but looking at the releases on GitHub openssl 3.4.0 is 17.5mb and rustls is 2.6mb. both of these releases are source files not binaries but I don’t see how rustls could possibly be larger than openssl.

Comparing source code sizes is completely meaningless. Rust projects are usually smaller with far more granular dependencies.
