With the large performance increases brought by the more recent versions of Python, it's not clear to me that installing this is faster than just upgrading Python. It is more simple though I'll give you that. If it also faster with more recent versions?



I believe the article answers all your questions!

(Also, IMO, it is much easier to install Pyston-lite than upgrade a whole Python version, which is an absolute nightmare on some of my specific scenarios with somewhat embedded hardware)

They are currently stuck on 3.8, but believe they will be able to support multiple versions easily because pyston-lite is much easier to develop for than pyston (because it is an extension and not a whole CPython fork).

They also present benchmarks at the very end comparing Pyston, Pyston-lite and the latest CPython 3.11.0b3, all compared to Ubuntu's default Python 3.8.10. It shows that while CPython offers ~8-15% improvements (macro-micro benchmarks), Pyston-Lite offers 8-27% improvements and "OG" Pyston offers 35-65% improvements.

So compared to regular CPython you might get an extra 10% or so, which might or not be worth it depending on your case. Excited to see what happens if they port Pyston to Python 3.11, though!
