Does this mean the benchmarks on https://github.com/niklasf/rust-pgn-reader are no longer valid? Can one simply use an older version to still achieve those speeds?

The benchmarks (v0.12.0) are after this regression.

You can downgrade to v0.11.0 to use the mmap based reader for even better speeds, but there have been bugfixes in dependencies, added features, and there is some controversy about using mmap in Rust.
