Thank you. There is not, but on the readme you can find a few links to learn more[1].
I don't have solid metrics, but using only JS for a previous attempt, I couldn't have 8 points running smoothly [2]. Now it works with 500[3].
I'm not sure whether it's because I have a better understanding of the problems now or just because Rust/wasm is way faster, but what is sure is that Rust makes it easier to write performant code, even if it's harder to learn at first.

The springs are not damped yet, but for the main example, drag is enabled[1]. This continuously slows down the particles.
Drag is computed[2] for all the particles using something similar to the Drag equation[3].
Also, like electricslpnsld said, having a small enough time step helps.

Thank you for the feedback. I will look into this. Maybe the issue is only related to WebGL rendering.
