There are many, many things that could be the culprit:
1. How many glasses are we talking about here? A few hundred? And what is
the polygon count? Could it be that you are overloading your card?
2. Are you sharing Appearance objects, or at least materials? There is/was
a bug that the system slowed down when you used lots of different materials.
Since the materials are usually the same, just create one and use in many
places.
3. Are you sharing textures? Or does each glass have its own texture? If
the textures are the same, but you are instantiated multiple copies of the
same one, you would be better off to use the same texture in multiple
places.
4. If the shapes are duplicate copies, try using link nodes and shared
groups.
