Objects using the same material are incurring separate draw calls.

Hi.

I have a prefab consisting of a mesh (152 verts, 76 tris, uv,colors) and a mesh renderer using the Mobile/Diffuse shader with a texture sized 64x64 automatic compressed with mipmaps.

Now I use this prefab multiple times in the scene but each use costs me an additional draw call. What am I doing wrong here? I get the number of draw calls from the "GPU Usage" Pane in the profiler.

Thanks.
