# /bench
Builds Java and runs the full benchmark suite, then analyzes results.
## Execution Steps
1. Run `./scripts/bench.sh`
2. Extract metrics from `tests/benchmark/prediction/opendataloader/evaluation.json` using:
```bash
jq '{summary, metrics, table_detection, speed}' tests/benchmark/prediction/opendataloader/evaluation.json
```
3. Output summary:
- NID (reading order)
- TEDS (table structure)
- MHS (heading structure)
- Table Detection F1/Precision/Recall
- Speed (s/doc, total time)
4. Compare with thresholds in `tests/benchmark/thresholds.json`
5. Warn if regression detected
## Options
- `/bench --doc-id 01030000000189` - Run for a specific document only
## Notes
- Benchmark won't run if Java build fails
- First run installs Python dependencies via uv sync
