file transfer SMB or FTP stuttering a lot

I try to transfer file from my pc under arch linux to my NAS and during the transfer , the transfer hang every 15 secondes, continue 10 seconds and again ..;

As SMB or FTP it happens the same.

When i'm under Windows 10, i don't have at all this problem with this same NAS.
If you have any idea.


PS: the Share is mounted like this
sudo mount -t cifs //192.168.1.44/volume_2 /home/david/.share/dlink-gabriel-volume_2 -o username=david,password=***,vers=1.0

PS2 : i have a fiber connection and speed test give me near 1GB/s, the local network speed is normally 1GB/s

What are you using for transfer? If some GUI/file manager do you see the same issue with a  cp or so?

Re: file transfer SMB or FTP stuttering a lot

i  did the test with such command : sudo rsync -ah --progress  --force

Result : stuttering again and i suspect that the bandwith speed is not the 1Gb as it would thave to be, but under W10 the NAS respond at around 250-300Mb/s so it is not a problem on the NAS
Time to transfert 6mn30s for 4.7 GB means 12MB/s under ARch Linux, under W10 i'm at 30-35MB/s

Don't bump, https://wiki.archlinux.org/index.php/Co … ct#Bumping
Have you done any further investigations?

If this is across protocols (smb + ftp) and not a GUI client trying to preview the transfered files, the cause is most likely the network connection.
=> Check your journal dmesg.

As for common pitfalls, post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

and (because you mentioned windows) see the 3rd link in my signature.

It may be worthwhile double-checking your firewall settings. I had a similar issue transferring files over SFTP, and realised that my firewall was configured to LIMIT ssh connections - rather than ALLOW them - which was causing 'hiccups' and odd 'hangs' during multi-file and long transfers.
