Conclusion
The key factor for a model to perform well is to keep both the number of draw calls and triangle count as low as possible. Some CAD programs give the option of choosing how high the resolution of the exported 3d model should be for some formats, put it in the lowest if you get this option. Blender can then be used to polish the model and export it as a .glb file. Make sure to open the model in an online viewer that can give a report to ensure that it’s performing well.
