I usually pick up models in these two ways，  
One is by binding an actionManager to the mesh，  
The other is to add a click event to the scene.

When the scene has a lot of mesh，  
The latter seems to have a higher performance cost.

I want to get the mesh and triangle of the current click, and I want to get the best performance

If you have a lot of meshes integrating octrees will be a good approach, see [Optimizing With Octrees | Babylon.js Documentation (babylonjs.com)](https://doc.babylonjs.com/features/featuresDeepDive/scene/optimizeOctrees)
