+# Benchmarking
+
+These are some files to determine performance of rustpython.
+
+## Usage
+
+Install pytest and pytest-benchmark:
+
+    $ pip install pytest-benchmark
+
+Then run:
+
+    $ pytest
+
+You can also benchmark the Rust benchmarks by just running
+`cargo bench` from the root of the repository. To view Python tracebacks during benchmarks,
+run `RUST_BACKTRACE=1 cargo bench`.
+
+You can bench against a specific Python version by running:
+
+```shell
+$ PYTHON_SYS_EXECUTABLE=python3.7 cargo bench
+```
+
+On MacOS you will need to
+add the following to a `.cargo/config` file:
+
+```toml
+[target.x86_64-apple-darwin]
+rustflags = [
+    "-C", "link-arg=-undefined",
+    "-C", "link-arg=dynamic_lookup",
+]
+```
