Benchmarking Rich

This directory contains benchmarks, for monitoring the performance of Rich over time.

View the benchmark dashboard here.

The benchmarks use a tool called Airspeed Velocity (asv), and we've configured it in asv.conf.json.

Running Benchmarks

We strongly recommend running asv run --help for a full list of options, but here are some common actions:

• You can run the benchmarks against the master branch with asv run.
• To test the most recent commit on your branch asv run HEAD^!.
• To generate a static website for browsing the results, run asv publish. The resulting HTML can be found in benchmarks/html.

The asv docs have some more examples here.

Updating the Benchmark Website

1. Ensure any tags you wish to benchmark are included in the file asvhashfile at the root of the repo.
2. Run the benchmarks for those tags by running asv run HASHFILE:asvhashfile. This will take several minutes.
3. Create the HTML locally for those benchmarks by running asv publish.
4. Run asv preview to launch a local webserver that will let you preview the benchmarks dashboard. Navigate to the URL this command gives you and check everything looks fine.
5. Checkout the rich-benchmarks repo from here and cd into it.
6. Copy the HTML you generated earlier into the root of this repo, e.g. cp -r ../rich/benchmarks/html/* . (assuming you checked out rich-benchmarks alongside rich in your filesystem)
7. When the HTML is merged into main, the benchmark dashboard will be updated automatically via a GitHub Action.
