**Short description of error**
Undo - To undo one step takes very long!
**Exact steps for others to reproduce the error**
I now had the time to prepare a testscene. At the Blender Conferece I think Sergey said, we should send a file to repoduce the problem. He or another developer will have a look!
The scene reflects the object and polycount, we have in our production files.
In other programs we use, with the same poly and object count, undo works in a second. So the object or polycount couldn´t be an excuse.
Open the attached Scene
Select one cube.
Rotate the cube.
Undo that step by clicking Ctrl+Z, count the time that it takes. On my system it was about 1m 6sec. Thats a lot for only one undo step!
Please make undo faster!
I tested the attached scene on two different computers.
One at work. AMD Threadripper 1950X 16CoresQ3,4 GHz - here it takes 1min6sec do undo the cube rotation.
One at home. Intel Xeon E5-2697v3 2x14Cores@2,6GHz - here it takes only 21sec do undo the cube rotation.
The difference between this two computers is interesting.
But that is only one undo step. Undoing multiple undo steps takes longer.
I hope it is worth to investigate it further?!
