> We also tested Rustls and its rustls-openssl-compat layer. Rustls could be an interesting library in the future, but the OpenSSL compatibility application binary interface (ABI) was not complete enough to make it work correctly with HAProxy in its current state. Rustls is actively working on improving the OpenSSL compatibility layer. Hopefully we'll have it fully working for HAProxy soon! We've also invested a lot in performance. Next week we'll be publishing a blog post about Rustls server side performance. Since it's relevant to discussions about TLS stack performance, here's a preview: https://docs.google.com/document/d/1xFoRjb7pn4ZtL5BH7_ZwXNgNpSCLPiYAIQ1BcSalY9w/edit?usp=sharing https://docs.google.com/document/d/1xFoRjb7pn4ZtL5BH7_ZwXNgN...
