Unless you need 3.9+ features, we’ve found Pyston to be considerably faster than any of the recently performance oriented CPython releases.

Have you tried PyPy?

Yes, we found PyPy is only marginally faster for our use case and chose Pyston instead due to better compatibility and no pesky warm-up periods.

When the Gentoo maintainers force me to is my answer. Minor version upgrades are a pain in the ass every single time.
