cifs - poor upload speed compared to rsync
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.
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.?
