What you did

Loading a scene using gltf

What went wrong

It took roughly 50 seconds to load a single model in release mode. By comparison, I loaded the same model here https://gltf-viewer.donmccurdy.com/ and takes less than a second to load.

Additional information

Here's the file I used. It's a model I exported from ue5. https://www.dropbox.com/scl/fi/ihcf4wttx1edc09gedoc6/idle_relaxed.glb?rlkey=jdsw4wm0ehjrof5m65ney4dvd&dl=0

I don't have those kind of loading time using the scene_viewer example

gltf-loading-time.mp4

Could you give more details on your CPU and hard drive? And try with that example from Bevy repo?
