Faster performance

I’ve found this site :
which is based on Cesium, and it’s performance is awesome.
Could You give such minimal configuration for performance please ?

No one ?! There is no minimal configuration for performance like in this site ?!

The default settings in CesiumJS should make your application as performant as possible. If it’s not, there might be something your app is doing that is causing this bottleneck, or you might have found an area in the library that could be improved. There’s no way to know without knowing more about what your application is doing.
