Steps to reproduce
1. Open user attached project
2. Add scenes 'ResourceScene' and 'EmptyScene' to build order
3. Build apk and deploy to device
4. Press 'Add resources' button (Adds 2k objects using Resource.Load and instantiates them). Once is enough, using more increases scene change time even more)
5. Press 'Change Scene'
6. Note how much time it takes to change the scene

Expected behaviour: about the same load time using devices with the same hardware
Actual behaviour: The load time is multiple times longer on some devices
