SMB to SMB performance

I experience the same. I usually SSH to the box to move data instead of doing it over SMB...

Is your network gigabit? your router gigabit? It's like you are only getting 100MPS speeds for some reason. Do both pcs have gigabit nic?

Are the nics the same in both OMV machines? Do you have virtualbox installed on both? Put a vm on the virtualbox plugin and test each machine against it's own vm, do with bridged adapters (not NAT). Also, do you have a spare cable. Change out cable going to each machine and see if that helps. If you find machine making the problem via the vm testing it may be a nic/driver issue. If changing cable fixes issue you know it was bad cable. Just some ideas.

You said, "If i copy, from the windows explorer, from Share A to share B i see the slowdown. If i copy, from windows, from Share B to Share C i also see the slowdown"

On these 2 examples your windows machine is a monkey in the middle. You are taking data from share A to your windows machine and then to share B. It is slow because it is going between 3 machines. If you did copy via command line on the OMV machine from share a to b this would not happen.

Same is true the way you do share b to c. Copy from OMV share B to your windows machine then to share C... SLOW. Try in command line to copy b to c right on the OMV.

You will especially see slowness in this type of copy if you are on laptop due to copy from share b then wireless to laptop and lastly wireless back to share c. It's crazy. If you moving data on same machine just use cp command

e.g.
cp /media/uuid of disk1/sharea/filex /media/uuid of disk2/shareb/filex
or
cp /media/uuid of disk2/shareb/filex /media/uuid of disk2/sharec/filex

you get idea and make correct paths. No monkey in the middle to slow you down. If you do things the way you did with 3rd pc in the mix expect it to be slow. What you did pc in the middle I never do. Why would you go thru LAN when you can copy via internal SATA to SATA. What do you think is fastest????

Actually, when testing some more it's not only between disks, it seems any copying between SMB shares at all is this slow. So even if the shares are on the same disk it's still this slow.

I'm suspecting that the data is actually going over my client PC.

Of course it is going over your PC. But still, the drop in speed is enormous...

But I'm not Desktop with teamed 2Gbit and OMV with 1Gbit.

There is an ajaxplorer .deb file somewhere people are using for omv. I use webmin's file explorer or command line. You can also "apt-get install mc" for Midnight Commander. If you search forum you can find how to install webmin.

The whole point of my comments was that you should not have the pc your on be in the middle of the transfer Tom. Figure out how to get data going from pc to pc, or share to share, with nothing in the middle. Do not use SAMBA to transfer from share to share on same OMV. Do not use SAMBA while on PC X to transfer from share A on OMV 1 to share B on OMV 2. You want direct as possible transfer.

In share A to share B on same OMV:
use cp command
or
use a filemanager on that OMV

In share A on OMV 1 to share B on OMV2:
I have vnc installed and vnc into desktop on receiving OMV2, browse network, copy from OMV1 and paste.
or
vnc to desktop of receiving OMV2 and use chrome and webmin to download from OMV1.
or
you could setup ftp on OMV1 and ftp in command line on OMV2 to get file (alternative vnc to desktop and use Filezilla to get file)
or
you can get files via SSH from OMV1 to OMV2. You can use sftp, or scp, while in SSH session. This is your best bet. Just Google and you'll see how to do it.

I don't have time to teach all this stuff. VNC is hard to setup for beginner. I use SSH tunnel for my VNC sessions too.

This gives you some ideas. For some people if they have their OMV at a desktop, and not in the basement like me, perhaps it is good idea to do full install of Debian then add OMV on top. Then they would could use Filezilla easily or just copy and paste via network browsing.

Sorry to bring up this old thread again. I also encountered this issue as simonp2. I then realized that the SMB TO SMB copy was actually gone through my laptop. It seems to me that this is a typical SMB implementation, that is, copy everything via NIC even if those SMB sharefolders are on the same disk.

I have a early model of Netgear NAS. I remember that Netgear actually implemented the SMB-to-SMB copy to bypass NIC if sharefolders are actually on the same disk(or same computer) but you have to log in the SMB using admin account. If you log in as guest, the NAS still handle SMB-to-SMB copy via NIC.

I just wonder if Volker can implement this feature in the future!

[...]that is, copy everything via NIC even if those SMB sharefolders are on the same disk.

That is why I have an extra share for this kind of administration things to move stuff around on the same disk.

If I remember correctly to my old "I set up my own network share with a debian server" times, debian already handled it that way! But I just tested, OMV doesn't...

What netgear NAS? I can't find anything about this. I would think you would have to modify samba itself to do this.

It is Netgear Readynas duo. I can't recall where is the thread now. You have to log into SMB using admin account. And you will see extra folder "c" which is the root folder. You have to double click into "c" folder to navigate various folders,then perform copy-and-paste to enable local disk copy.
