+Perf tools for page-level parsing benchmarking.
+
+Usage
+- Install extras for optional parsers (not part of main package):
+  - pip: `pip install .[perf-tools]`
+  - uv (already configured): `uv sync --group perf-test`
+- Run on a file or directory:
+  - `python perf/run_perf.py ./docs/sample.pdf`
+  - `python perf/run_perf.py ./dataset --recursive -p pdfplumber`
+
+CLI
+- `input`: PDF file or directory of PDFs.
+- `--parser|-p`: one of `docling` (default), `pdfplumber`, `pypdfium2` (alias: `pypdfium`), `pymupdf`.
+- `--recursive|-r`: recurse when input is a directory.
+- `--output|-o`: output CSV path (default under `perf/results`).
+
+CSV columns
+- `filename,page_number,elapsed_sec,success,error`
+
+Statistics
+- Prints totals, avg sec/page, min/max, and percentiles (p50/p90/p95/p99) after the run.
+
