The article you quote specifically is about 1.1.1 versus 3.0.7, whereas the comment you are replying to is about 3.5.x

(3.0.0 was released in September 2021, 3.5.0 was released in April 2025, and a significant chunk of the work during those 3.5 years was focused on improving performance)

Since then, OpenSSL has improved performance such that it’s only 3x slower than it used to be.

It doesn't make clear what version is being referred to here, but it's implying a current version with "since then" - i would assume either 3.5 or 3.6.

pyca/cryptography folks have been complaining about openssl since the relase of 3.0, so, no, it's not a safe assumption

From the fact that the next paragraph is about them switching some non-cryptographic parsing operations to their own Rust code and getting performance better 1.1.1, I would assume that openssl 3.something was 3x slower than 1.1.1 when they switched, and they're not interested in profiling 3.5 or 3.6 unless they hear it's now significantly better than 1.1.1, not just about the same.
