I tried to load a model with 20,000 + objects（meshs）, but it became very sluggish

👋 hi there, for issues that aren't that pressing, that could be related to threejs etc, please consider github discussions.

How can I solve this problem ？

that's 20.000+ draw calls, and most likely lots of materials that aren't re-used. threejs and webgl in general doesn't work that way, you shouldn't have more than a few 100 drawcalls max. you need to instance re-occuring objects and re-use materials as much as you can.
