T56283 is related to this because the problem is the object link data.

Updates to this task:

I'm working in a redesign of the drawing engine to support instances. Before, the drawing engine was unable to use several obejcts with the same name. With the new design it's possible use several instances and there is a great speed improvement.

Example of one object with several collection instances.

I'm still working and when all will be ready, I will commit all changes to blender 2.8 branch.
