doc: update README performance claims to the final dashboard - #2894
Merged
Conversation
Bring the comparison bullets in line with the frozen dashboard data and the 'Why Lean is faster than Rust' blog post: fflate is dominated outright (denser and 1.5-2x faster at every level, >2x faster decode), not merely 'caught'; OCaml is 3-9x (not 2-4x); the libdeflate gap is ~2-10x (not 3.5-11x); and add the previously missing zlib-reference, zlib-ng/zlib-rs, Go/Zig, and decode-side comparisons, a link to the blog post with the whole-tar headline race, and two Known-limitations bullets (compression memory use, decode vs C-grade decoders). Refer to the implementation as lean-zip rather than 'native' throughout the comparison list. All figures recomputed from the frozen results/latest.json geomeans.

This PR update the README's performance comparison to match the final frozen dashboard and the "Why Lean is faster than Rust" blog post. The fflate bullet claimed lean-zip had merely "caught" it, when the final data shows outright domination (a single lean-zip level denser and 1.5–2× faster at every fflate level, with >2× faster decode); OCaml moves from 2–4× to 3–9×; the libdeflate gap tightens from 3.5–11× to roughly 2–10×; and the zlib-reference, zlib-ng/zlib-rs, Go/Zig, and decode-side comparisons — plus a link to the blog post and its whole-tar headline race — are added. The comparison list now says lean-zip rather than "native", and Known limitations gains the blog's memory-use and decode caveats. All figures are recomputed from the frozen
