In my project, I am showing sequential glb files to the users. Some of the files are around 1kB to 20MB, but there are some approximately 1GB files. I tested it with 0.99GB glb file and it took 8 seconds to load each time I tried. Is there a way to decrease this loading time. Are there any experimental results?
Probably in this case a set of smaller files suits better for possible hardware limits.
1Gb file may crash quite a lot of systems.
Meanwhile, 8 seconds to load such a big file seems a very good result.
I believe, you may also try to compress textures (KTX compression) to reduce the file size and loading speed.

You can try incremental Incremental Loading System | Babylon.js Documentation (babylonjs.com) or progressive Progressively Load .glTF Files | Babylon.js Documentation (babylonjs.com) loading too.
