Optimising iOS Level Load Times

I need some advice on how to improve my iPad game’s level load times. The main level for my game is currently taking roughly 10 seconds to load.

1. I procedurally create most poly objects, and an average frame will have from 250 to 1000 vertices

2. I’ve shrunk every texture to fit within 64x64 (they now consume less than 3mb). After shrinking all the textures the load times actually increased by one second

3. My sound load types are “Compressed in Memory”

4. I’ve compressed all my sounds to 32 kbps (they now consume roughly 500kb)

5. I’ve tried using Application.LoadLevelAsync to hide the load times, but the game freezes while loading… for ten seconds

Below is the Editor Log from building my current test scene. Any thoughts or suggestions?
