Why heavy comes twice

Because code repetition decides rankings, and most benchmarks do not say what theirs is. sqzass highlights each distinct block once per build, so a corpus whose generator repeats the same block is a different measurement from one where every block is unique — the gap between 187 ms and 1,298 ms is that variable. A single "heavy" number that does not state its repetition has hidden the thing that produced it.

Method

  • Cold. Before every run the output directory and each tool's caches are removed — .jekyll-cache, Astro's cacheDir and dist, Hugo's resources and build lock. Wall clock and peak RSS come from GNU time.
  • Corpus. 1,000 pages plus a section index. The markdown bodies are byte-identical across tools; only the front matter syntax differs. A paragraph is one fixed 76-character sentence repeated four times.
  • Highlighting is on everywhere, at build time, as each tool ships it: syntect + Oniguruma (sqzass), Chroma (Hugo), Giallo (Zola), Rouge (Jekyll), Shiki (Astro). Markup granularity differs — spans on the same heavy page: sqzass 3,205 · Jekyll 1,800 · Zola and Astro 1,700 · Hugo 600. sqzass emits the most detailed markup of the five and the numbers above.
  • Templates. Each tool gets the same minimal no-theme layout: an HTML shell around the rendered content.
  • Astro's time includes Node startup (~1 s). It is also doing more than markdown-to-HTML — it is a component framework. That is the honest caveat; the corpus is plain markdown, which is the workload this page is about.
