Short description of error
It takes 2 seconds to select or deselect vertices, edges or faces in Edit Mode. It makes it almost impossible to edit the model...
The model is not very complex, at 200k vertices.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
Enter Edit Mode and try to make changes to the model.

Interestingly, a lot of time is spent in
BM_loops_calc_normal_vcos.I'm not exactly sure if this is a bug, but I don't think it should be like this...
Please confirm that next build has improved on this. On the other hand, it seems that the undo system is doing a lot of things here.
I tried on today's build and it's slow the same way...

I cannot reproduce the problem in any version I test.
This must be a driver issue.
But I notice a small difference in performance when transforming the vertices. (Which is already addressed in #73360)
@GabrielMoro, can you test with one of the latest builds?
