Dear Maintainer,

Copying a file from a nfs share on hd1 to a nfs share on hd2 on the same server
gives a low throughput with dolphin and krusader.

The server/NAS is Openmediavault 7 (Debian 12 based) but same problem was
present with Openmediavault 6 (Debian 11 based).


Dolphin/krusader from hd1 nfs share to hd2 nfs share on the same nas through
nfs:

nfs4.2:
9 MB/s

nfs4.1:
50 MB/s

Thunar has no problems with nfs4.2


I found one other case of this bug:

https://forum.openmediavault.org/index.php?thread/47985-issues-with-server-
side-copy-using-manjaro-client-and-dolphin-file-explorer/


Copying files from the client to the NAS works correctly with Dolphin (90
MB/s).

This seems to point to problems with the server-side copy / copy_file_range
implementation in kio.
