Running cargo bench from the root of the repository will start the benchmarks. Once done there will be a graphical report under target/critierion/report/index.html that you can use use to view the results.

To view Python tracebacks during benchmarks, run RUST_BACKTRACE=1 cargo bench. You can also bench against a specific installed Python version by running:

$ PYTHON_SYS_EXECUTABLE=python3.7 cargo bench

Adding a benchmark

Simply adding a file to the benchmarks/ directory will add it to the set of files benchmarked. Each file is tested in two ways:

The time to parse the file to AST
The time it takes to execute the file

MacOS setup

On MacOS you will need to add the following to a .cargo/config file:

[target.x86_64-apple-darwin]
rustflags = [
    "-C", "link-arg=-undefined",
    "-C", "link-arg=dynamic_lookup",
]
