Description Luis Miguel García Mancebo 2018-07-02 13:41:00 UTC 
There are other bug reports about this issue, but the later of them is from 7 years ago, so I open a current one.

I have a directory with a git repository. Stats are as follows:

138 MB - 15200 files - 3100 folders

If I want to copy the directory to another place in my SSD, it lasts for 15 minutes.

If I do it manually with a "time cp -R", it lasts for 2,5 seconds. So something is going on when using Dolphin.

If I do a "right click / Compress / Here (.tar.gz)", it lasts for 8 seconds.

I don't know if the problem is the notification of the taskbar that shows the copying, or the individual process of each file, or very big data structures inside Dolphin as stated in bug #257907.

Summary:
* cp -R     2,5 seconds
* Compress:   8 seconds  (tar.gz)
* Dolphin:   15 minutes
