Benchmarks

ironmark is compared against:

• Native Rust: pulldown-cmark, comrak, markdown-it, markdown-rs and md4c.
• JavaScript and WASM: markdown-wasm, md4w, marked and Bun's built-in parser.

All parsers are configured for the same feature set: CommonMark plus GFM tables, strikethrough, task lists and autolink literals.

Run them yourself

pnpm bench:rust                     # native Rust (criterion)
pnpm bench:js                       # WASM under Node
pnpm bench:bun                      # WASM under Bun, incl. Bun.markdown.html
pnpm bench:js --file my-doc.md      # benchmark your own Markdown
pnpm bench:js --check               # verify the parsers produce the same output first
pnpm bench                          # everything, saved as a benchmark/history snapshot

pnpm bench needs md4c (brew install md4c) and Bun 1.4 or newer. For a fast development loop, pnpm bench:quick runs only ironmark in about 10 seconds; never commit those numbers.

See benchmark/README.md for every option, how to read the output and how to get stable numbers.
