Short description of error
Delete Hierarchy - To delete a hierarchy 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 reproduce the problem. He or another developer will have a look!
The scene reflects the object and polycount, we have in our production files. We often have to delete a hierarchy with lots of objects.
In other programs we use, with the same poly and object count, delete hierarchy works in a second. So the object or polycount couldn´t be an excuse.
Open the attached scene
Right click select Row7 in the outliner.
Choose delete hierarchy.
Count the time that it takes do delete. On my system it was about 20seconds. Thats a lot for only deleting!
Please make delete hierarchy faster!
I tested the attached scene on two different computers.
One at work. AMD Threadripper 1950X 16Cores@3,4 GHz - here it takes 20sec to delete the Row7 hierarchy.
One at home. Intel Xeon E5-2697v3 2x14Cores@2,6GHz - here it takes only 12sec to delete the Row7 hierarchy.
But that is only one hierarchy. Deleting multiple hierarchies takes longer. I thing it depends on the count of objects you delete.
I hope it is worth to investigate it further?!
