--- Comment #36 from Mauro Molinari <mauromol at tiscali.it> ---
I repeated my experiments after connecting the laptop to the Gigabit ethernet
(instead of WLAN). Here are the results:
- copy from NAS using smb:/ protocol in Dolphin: <14 MB/s
- copy from NAS using nfs:/protocol in Dolphin: <8 MB/s
- copy from NAS using ftp:/ protocol in Dolphin: <70 MB/s
- copy from NAS (using Dolphin) after mounting SMB share: ~60 MB/s
- copy from NAS (using Dolphin) after mount NFS share: ~21 MB/s (*)

(*) probably capped by the NAS CPU utilization, which was >90% (still
surprising for me, since I had expected NFS to be lighter and faster than
SMB...)

So, this clearly confirms what was observed by others, too.
