For speed.python.org, I run a script manually to "add a new dot" on the graphs. The script always pick the latest versions of pyperf and pyperformance. I also frequently update pyperformance requirements to get security fixes, bug fixes, but also support the latest version of Python: for example, I had multiple issues with Python 3.8.
The problem is now that graphs became meaningless because of significant performance changes in dependencies like sympy:
Is there a volunteer to regenerate all data on the latest version of pyperf and pyperformance? It would require to list all commits of previous benchmarks run (it should be as easy a listing the content of a directory, I can tell you more in private), run benchmarks on these commits (I have a script which automate everything), remove old CPython data (but keep PyPy data, who sent it by the way?), and upload new data.
Night gathers, and now my watch begins. It shall not end until my death.
