Vague. What's pretty close? I mean, even for IO bound tasks you can pretty quickly validate that the performance between languages is not close at all - 10 to 100x difference.
I'm saying that the Rust might execute in 50ms and the Python in 150ms. You are the one not making sense, we are talking about application performance, why are you not measuring that in milliseconds.
That is assuming Rust is 100x faster than Python btw, 49ms of I/O, 1ms of Rust, 100ms of Python.

Okay, so the Rust code would be 3x as fast. Feels arbitrary, but sure.

I explained why your post made no sense already...

That's not how anything works. Different languages will perform differently on IO work, different runtimes will degrade under IO differently, etc. That's why even basic echo HTTP servers perform radically differently in Python vs Rust.
This isn't how computers work and it's not even how math works.
This conversation has become nonsensical. The thing we can agree with is this - no, uv would not be as fast if it were written in Python.
