Benchmark Index
Measured performance across Gray execution layers, release candidates, and controlled hosts.
Resident strict typed JSON: Gray Static vs Rust
Two retained runs each contain 61 paired rounds of strict flat JSON decoding plus checksum. Net duration subtracts the matched control; lower is better. Rust 1.96.0 with serde_json, Linux x86_64 on AMD EPYC 9645 (KVM).
| Run | Gray Static | Rust | Gray duration | 95% ratio interval |
|---|---|---|---|---|
| Run 1 | 1,282.650 ms | 1,523.771 ms | 15.82% lower | 0.8130–0.8638 |
| Run 2 | 1,260.596 ms | 1,502.832 ms | 16.12% lower | 0.8221–0.8651 |

Runtime leaderboards
Rankings never cross fixtures, hosts, metrics, or declared comparison scopes.
| Rank | Implementation | Variant | Result | vs leader | Trials | Environment |

Current Gray results by layer
Accepted Gray measurements only. Values remain on their original fixture scales.
Reference map
Preflight connects Gray evidence to recognizable benchmark families without treating external results as Gray-controlled proof.
One benchmark answers one question.
Gray can beat a reference on a scoped fixture before it proves a broad language claim. The map separates measured Gray evidence, public comparison families, and future targets.
References users recognize
These lanes help readers orient Gray against common systems, web, and scripting ecosystems.
Known benchmark families
External suites are linked as context. Preflight only upgrades a claim when Gray-controlled evidence is imported with source, host, samples, gates, and limits.
Where each Gray result belongs
Plain-English categories for technical readers, founders, customers, and researchers reading the same evidence.
