Containerbase.mk_copy extremely slow and memory hungry

Is there an existing issue for this?

Current Behavior

Copying 500 descriptors in a loop took 25 seconds and consumed 5 Gigabyte memory.
The reason for the memory consumption is that copying the node via xml_utils.copy_element seems to copy each time the whole tree below the node.
The slow speed is caused by

• XPath expression is involved
• a lot is copied
• • the computer starts swapping after a certain time.

The whole copy node thing is unusable for use inside sdc11073, esp. in transactions.

Expected Behavior

faster

Minimal Reproducible Example

Solution proposal

change the default copy_node to False. This cures all problems inside sdc11073.
