Phase 4 API Baseline

This baseline measures API framework overhead using the local FastAPI app with a stubbed orchestrator response.

Command

PYTHONPATH=. .venv/bin/python scripts/perf_baseline.py

Results

• requests: 200
• concurrency: 20
• average latency: 14.91 ms
• p95 latency: 19.54 ms

Notes

• This is not end-to-end RAG latency because retrieval and LLM generation are mocked.
• Use this baseline to separate framework overhead from model/runtime latency when running full-load tests.
