System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce RTX 3090/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 461.40

Blender Version
Broken: version: 2.91.2, branch: master, commit date: 2021-01-19 16:15, hash: 5be9ef4177
Worked: tested 2.83 LTS and similar times for object move

Short description of error
The time it takes to undo an object move increases based on number of faces in scene.

Exact steps for others to reproduce the error
Copy and paste many high poly models in one Blender file or use Shift+D reproduce similar times. Alt+D is MUCH better, but is only relevant for duplicating the same model. If there are many models of different geometry in one scene there is no way around a long undo time on object undos. I specify object undo because as you can see at end of attached .gif in edit mode undos are much faster, which i think is a byproduct of a recent update to the undo system.
Default startup

By comparison, undos in a 60million face scene in 3ds Max are instantaneous

Sorry this took so long to answer.

Performance improvements are always welcome of course, but these are not handled on this bugtracker, see the following policy:

Thanks for the report. While we do continue to work on improving performance in general, potential performance improvements are not handled as bug reports.
To improve performance, consider using less complex geometry, simpler shaders and smaller textures.

Sorry to be strict here, but will have to close, thx reporting anyways!
