In my case, there are hundreds of tiles in my tileset. The tileset size is about 600mb and the max tile size is about 20mb. After use gltf-pipeline (-d default) to compress the tileset, It 's about 300 mb.

The problem is that the tile renderring in browser become too slow. When 600mb, the tileset renders in sceconds. But now, it renders in minutes.

additions: my browser is chrome and I add mime-type wsam to web server. the cesium version is 1.52. and the 3d tileset model is an oil & gas plant which contains thousands of assets, such as pipeline, equipment, instruments in a rectangle area.

Hmm, that's unexpected. @lilleyse any ideas?
