cifs - poor upload speed compared to rsync

Asked by Florian Schwarz on 2018-07-18

I'm mounting folders from my NAS on my computer (Ubuntu 18.04) with cifs. Copying an 8 GB file...

Upload (local -> mounted)
- Nautilus/Nemo -> 6 MB/s
- rsync -> 50-60 MB/s

Download performance is also strange, but not my biggest concern.
Download (mounted -> local)
- Nautilus/Nemo -> 90 MB/s
- rsync -> 50-60 MB/s

rsync command (upload):
rsync --progress /home/me/file.iso /mnt/cifs_media/

fstab entry:
//nas/media /mnt/cifs_media cifs vers=3.0,uid=me,gid=me,credentials=/home/me/.smbcredentials,dir_mode=0700,file_mode=0700 0 0

Any idea, why the file managers are uploading up to 10 times more slowly than rsync, although both using the same cifs, os, hardware, network etc.?
