Increase load performance

Hello,

I developed a small application that uses a 3d world with a lot of vertices.
If I tried the application (real iPhone 3g) more than 2 minutes is needed to show the world.

I already optimized the mesh in blender! Are there any more places where I can improve the performance?
Wit the instrument I see that a lot of the time is spend at: sio2ResourceBindAllPhysicObjects (about 12 %) and findOrAddVertex (about 14%).

Thanks a lot for your help

Send me the .blend by email with packed textures, so I can check where you can optimize...

(of course whatever you send me is under your NDA)

Cheers,
