How to improve the performance of physical scenes?

[syzdev]

My goal is to use ammo.js build a slightly larger physical scene: about 10000 boxes. (Maybe not so much, but the more the better)

But it's obvious that Browsers can't afford it.

So I want to ask you for help:

1. Are there any ways to optimize performance in ammo.js?
2. Are there any ways to optimize performance in three.js for ammo.js?
3. What other suggestions do you have for building large physical scenes?

Thank you in advance. : )

Uh, I think browsers should definitely be able to handle 10k boxes. Do you have some sort of way to showcase your problem online? I'd be happy to take a quick look if you want.

there were examples https://lo-th.github.io/phy/index.html?E=physx#million
And to improve the performance:
-simplification of the collider mesh (the simpler and smaller the mesh and the number of vertices) - the faster the calculations.
-solid primitives are easier to calculate than composite ones from triangles
-simulation step
-CCD... etc
