The benchmarks aren't quite ready to be widely disseminated yet. With that said, I do record benchmarks from time to time in the repo to track progress, which you can see here: https://github.com/rust-lang-nursery/regex/tree/master/bench... --- You'll have to do the comparison yourself though.
My plan at the moment is to publish something more comprehensive, but it will take time.
And yes, the benchmarks you linked are not only outdated, but misleading, and parts of the conclusion I do not agree with. It also doesn't include PCRE2, which is very fast.
There is some analysis---only for Rust's regex engine---with the definition of the benchmarks themselves: https://github.com/rust-lang-nursery/regex/blob/master/bench... (If you fish around there, you'll also see how everything is wired up.)
