Why 
--no-pantsd
? That's exactly the case PyPy should be bad at.
Pex CI could have told you in advance that cold PyPy is bad

because 
--no-pantsd
is the case that folks have the most performance issues with (either due to cold runs in CI, or due to 
pantsd
restarts)

Ok... well we wrote that off years ago. Pants simply doesn't work without pantsd almost by design.

but if the JIT can’t get warmed up in 80s, it’s not going to be helpful here.
i expect that it would be worth it to begin reimplementing the innermost non-plugin/core objects and rules in Rust.

we’ve done it piecemeal, but not in a concerted way. and i think that doing it in a concerted way could make a significant difference.

Presumably s/python/js/ would make a huge difference as well. Python is not awesome.

So can it be said?: "We cannot have our ~pie~PyPy, and eat it too"

s/python/js/
@enough-analyst-54434 I assume you mean s/python/rs/ … JavaScript would not be a good replacement for python 😛

I definitely mean js (or ts). It performs well / has been optimized to death; so seems like the right scripting language replacement.

I see. js/ts might be performant, but I would not be performant at writing it…

And so say the ts people that we force Python on. You'll always make someone unhappy on language. I'm just at the perf.
