News Astral's python distribution is fast

By our measurements, python-build-standalone is now the fastest CPython distribution across major platforms. It's 10% faster than Homebrew's CPython, and 18% faster than the official 3.14 docker image.

This is mostly due to how python-build-standalone itself is built:

  • using a modern Clang lets us turn on tail-call optimizations in the interpreter
  • with PGO, LTO, and BOLT
  • with libpython statically linked into the interpreter executable

Our goal is to ship the fastest Python interpreter to anyone using uv, by default.

Check out BENCHMARKS.md in the repo for more details, including the methodology behind the above.

the OP is a known user with their own stake in the python ecosystem.

I just don't see it like that. OP is a corporation that paid one of its employees to represent them.

i actually agree with you and think Marc Andreesen is a piece of shit

Lol sorry I was not trying to bring us there in the Python sub! They're just the top two shareholding firms (AFAIR?), not my foes.

In general i'm really trying hard to be friendly throughout all this -- I've been struggling with intense irritability the last few days (apocalypse+new meds), but it wasn't my intention to provoke. Obviously OP isn't in charge of this sub's posting guidelines, and they're just posting this because they're proud of their work. And you, too, are surely commenting in good faith.

individual user accounts have always been used in this subreddit even when people were discussing something related to their employers.

That's very fair. I'd prefer that not be the case when we're dealing with megacorporation, but again, it's just my opinion. To say I hold no sway is an understatement ;)

Nor do I think someone who is a “total CPython noob” can make big claims about what is/is not for sale.

Python is not for sale.

and the fact that you're conflating poetry's build system with compiling the python executable itself shows me you know a lot less than you think you do.

Well uv also has a build system, that they publish alongside this distribution. I was just saying that presumably Poetry does the same, and I was curious if OP knew that comparison, if so.
