🏆 WORLD_RECORD_DECOMPRESSORS
Label (Rickard, 2026-07-13): znippy-zoomies holds world-record-class decompression — flag it, guard the numbers, don't let a regression slip in unbenched.
What this repo is
The codec + concurrency leaf the whole constellation stands on:
- Decompressors / codecs:
lgz·ljar·lzip-parallel·lbzip2 - Concurrency primitive:
gatling(work-stealing) — the suite's shared parallelism engine (reuse it everywhere; never hand-rollthread::spawn). - OSM path:
osm-katana(convert bench vs osmium/osmconvert).
The claim (guard it)
Recorded standout results (see the mashup/GATLING sections in the docs + the znippy-zoomies_agents_problems.md bench log):
- zoomies-lbz2 ≈ 808 MB/s > lbzip2 ≈ 764 MB/s (the earlier "lbzip2 beats us" note was flipped).
lgzcore-scaling analysis; planet Sweden-clip all-core face recorded.
Standing rule
Any change to a decompressor's hot path MUST re-run its bench and keep only if faster AND byte-identical (roundtrip-verify). Heavy benches run on the quiet bench box (Loki/Odin), never inflate on a busy box. Bench data → /home. This label exists so the record is never quietly lost to an unbenched regression.
