Slow transfer rate from WIN10 to OMV with WinSCP

shecky66 · 25. November 2021

Hi at all!

I often transfer files from my Windows 10 PC to my OMV server with WinSCP in SSH.

The transfer speed is always very slow: it starts at 11MB / s and, on average, never exceeds 5 - 7 MB / s.

Computers are connected with ethernet cables via D-Link DGS-100SD switch with 10/100/1000 Mbps ports.

Is there any optimization to be done to achieve higher transfer speeds?

This is network interface card information on OMV:

Ciao amico,

If you're transferring large files like a TV show in your screenshot, you should use SMB, which is way faster

raulfg3 · 26. November 2021

please use SMB instead.

shecky66 · 28. November 2021

With OMV WebGui I have created a SAMBA share, but the transfer rate does not improve...

Can anyone help me to write an optimal configuration?

Thanks!

please use iperf3 to test your LAN and post result.

iperf3: parameter error - must either be a client (-c) or server (-s)

Can you give me a more specific command?

Jirri · 29. November 2021

I use SMB

I had the same problem Win 10/11, the problem was on the Windows side.

I solved according to this video, now the transfer speeds start at 110 MB / s and stabilize around 90 MB / s for large files.

I think the settings in the video are not just about SMB, maybe it will help you.

Please use google to find how iperf works.

NO WAY, DO NOT USE SMB 1.x!!!!

You should not trust random and unreliable tutorials on Youtube.

shecky66 please provide more details.

Are you transferring a large file?

Is your client and OMV both connected to ethernet?

What Hardware is OMV? If you're using a slow CPU system like an old RaspberryPI, you might have to tweak some SMB settings.

Monitor OMV server performance when copying a file.

Roysen · 29. November 2021

I have the same speed on SMB transfer but when using iSCSI from the same server my speed is 120 MB/s. So there needs to be some problem with the SMB system en most likely with the SMB protocol since I got the same speed between two Windows boxes on my network.

I usually transfer multimedia files (photos, videos, music) ranging from 1 Mb to 25 Mb.
Client (Windows 10) and OMV are connected via ethernet by switch D-Link DGS-1005D (5 port Gigabit 10/100/1000 Mbps)
OMV use an AMD Phenom II X4 940 processor
In attach is the log obtained with the following command iperf3.exe -c 192.168.xxx.xxx -P 50 -fg -t 5 launched from the Windows 10 PC with OMV listening as a server (log taken from OMV after command iperf3 -s)

It looks like you are connected with a 100MBit/sec network.

iperf tells something about 90 Mits/sec which is roughly 9 MB/sec.

raulfg3 · 29. November 2021

Yes , I Agree.

Because your switch & NIC are 1000 Mits/sec capable, please try to change cable , use cat 6 , and if still same throughput, try to use a direct cable betwebeen your NAS and your PC to measure with iPerf3 and eliminate the switch from equatrion.

I have a 1Gb net but am still getting like 11MB/s and as I said before getting nice speed on my iSCSI drive on the same server. What kind of tweaks is possible in SMB?

Please read apropiate section on forums:

Network

CIFS/SMB

eg: Windows shares / samba Trouble shooting

and finally google a bit: https://www.maketecheasier.com…-registry-editor-windows/

At the end, you need to test diferent teaks and select ones that works for you.

As said by others, you're connected at 100 Mbps.
Please check your setup

Win 10 or OMV setup?

Check if both systems are connected to 1000 Mbps, at least one is not so you could try to change cables

Or any router settings like the green mode of my Fritz Box.
