[1]Rustls as a modern TLS library written in the Rust programming language has long been showing [2]promising performance and competitive to OpenSSL and other alternatives. In a fresh exploration of Rustls server-side performance, it's easily beating OpenSSL.

In a new blog post looking at Rustls server-side performance, the latest state of this Rust TLS library is very promising. For those just wanting to know the key takeaway:

"Current versions of Rustls show competitive performance when processing many connections at the same time on a server. Rustls servers scale almost linearly with the number of cores available, and server latency for the core TLS handshake handling is roughly 2x lower than OpenSSL in our benchmarks."
