 working solely on the bindings.

+## Benchmarks
+
+- Requirements:
+  - protoc: install `protobuf-compiler` (Debian/Ubuntu: `sudo apt-get install -y protobuf-compiler`).
+  - Optional: gnuplot for Criterion's gnuplot backend; otherwise the plotters backend is used.
+
+- Run (from `rust/lance-graph`):
+
+```bash
+cargo bench --bench graph_execution
+
+# Quicker local run (shorter warm-up/measurement):
+cargo bench --bench graph_execution -- --warm-up-time 1 --measurement-time 2 --sample-size 10
+```
+
+- Reports:
+  - Global index: `rust/lance-graph/target/criterion/report/index.html`
+  - Group index: `rust/lance-graph/target/criterion/cypher_execution/report/index.html`
+
+- Typical results (x86_64, quick run: warm-up 1s, measurement 2s, sample size 10):
+
+| Benchmark                | Size      | Median time | Approx. throughput |

 ## Python Bindings
 
-Python bindings for this crate live under `python/src/graph.rs` and expose the same configuration and query APIs via PyO3.
-
-### Python Examples
-
-See top-level `examples/` for runnable Python examples:
+See the Python package docs for setup and development:
 
-- `basic_cypher.py`: simple node filter and projection against in-memory Arrow batches.
-- `kg_traversal.py`: two-hop traversal on a small synthetic knowledge graph.
-
-Setup and run (from repo root):
-
-```bash
-Option A - Local build (editable):
-
-```bash
-maturin develop -m python/Cargo.toml
-python examples/basic_cypher.py
-python examples/kg_traversal.py
-```
-
-Option B - Using uv:
-
-```bash
-uvx --from maturin maturin develop -m python/Cargo.toml
-uv run --with pyarrow python examples/basic_cypher.py
-uv run --with pyarrow python examples/kg_traversal.py
-```
-```
