shader help for IOS

Dear Friends,
i am facing an alpha issue on diffuse shader, when i applied the Transparent> cut out > Diffuse shader it solve the alpha issue, but it effect the performance of the game on Iphone , iPad.

Can anyone help me how to make Transparent> cut out > Diffuse shader for IOS friendly,

Advance Thanks

Cutout on most mobile devices is far more expensive than regular transparency.

The only real way to make it cheaper is to edit the actual mesh to cut away as much of the transparent areas as possible (thus reducing the number of on-screen pixels you have to perform the cutout on).
