Moving this to the Unity tech talk forums.

In forward rendering each light adds an additional pass, so if you have just a default directional light in your scene then it would double your vert count

Vertices are split along UV edges, material borders, smoothing groups.. this will be calculated into Unity's vert count as well.

Turn off the read/write flag on the mesh and it will cut the memory used in half.  Doing this means you will need to do manual refresh every time you change the asset.

Models

Disable the Read/Write enabled flag

TheRead/Write enabled flag for models operates identically to the one described for Textures. However, it is enabled by default for models.

Unity requires this flag to be enabled if a project is modifying a Mesh at runtime via script, or if the Mesh is used as the basis for a MeshCollider component. If the model is not used in a MeshCollider and is not manipulated by scripts, disable this flag to save half of the model’s memory.
