Copy speed transfer slow

Help and Support
1

Hi Everyone,

Sorry to create a new post on that one, but after spending hours to read many other threads, I’m struggling to find a “real solution”.

My problem is the following:
When I transfer a file via SFTP (Filezilla) from my computer to an HDD external connected to the Vero4K device, the speed transfer is super slow… not exceeding 4.8MB/s)

osmc

My configuration:
Laptop connected on 5Ghz wireless
Vero4k connected to the same network (I tried both: wireless & wired, same result)

Technical information:

My external HDD:

Copy from Vero4K to the HDD via rsynch

iperf3 from Verok4 to the laptop:

iperf3 from laptop to Vero4K:

Any solutions/explanations will be appreciated

4.8 megabytes per second is 38.4 megabits per second, which is not very far away from your measured network speed from laptop to Vero; so it seems like the network speed might be the limiting factor.

Yeah, better to just move the hard drive to the computer and copy it there.
I would power off the Vero before removing the hard drive, though.

Hi,

Yes it was my first reaction as well, but this limitation seems to be due to the Vero4k network performance itself rigth ?
As I got the same perf in wireless or wired ?
Also my laptop is capable to go up to 50Mo/s in wireless, so the problem is defenetly not my local router.

I was also considering to unplugged/unplugged the USB drive everytime, but not really convenient with all those powercable behind the TV furniture :confused:

You have iperf3 with 48 Mbit on wired, that would be strange. Check iperf3 on wired and we look from there.

As fzinken says, it would be a little surprising if the Vero’s network speed was limited to 40Mb/s on wired Ethernet. (If is, there’s certainly something odd going on). As well as checking iPerf numbers with the Vero connected by wire, you might also want to get some numbers for when both the Vero and the laptop have a wired connection - it could be that the laptop’s upstream speed over WiFi is slow.

Also, is this a Vero 4K, or a Vero 4K+?

And, when using wired connections, are both devices connected directly to the router, or are there other devices involved (e.g. an Ethernet switch or a power line adapter)?

The screenshot was done when the Vero was wired connected.
And I have a Vero4K+

Setup is:
Laptop connected to Wireless router
Vero4K+ connected in Wired to the same wireless router

8

Then you only have a 2.4 Ghz connection as it seems.
As that connection is only 48 Mbit. Which wifi technology does your Router and Notebook support?

9

I’m connected in 5Ghz
In fact, if I want to download something from my laptop, I easily reach 50Mo/s

10

What is 50Mo/s???

Iperf clearly show that you get 43Mbit/s.
Can you connect you Laptop wired to the router?

11

Sorry, I meant: 50 MB/s :slight_smile:

12

Are you positive that’s 50 megabytes per second and not 50 megabits per second?

It’s also possible that the laptop’s upstream network speed is much slower than its downstream speed.

What iperf3 result do you get when both the Vero the laptop are connected to the router using a wired connection?

13

Yup, 100% positive

Just did a quick speedtest on Internet just to show you (not fully reflecting reality as I have a fiber 2Gb link, but still)
In fact the upload is even better than the download, so I should be able to upload even faster to the Vero :slight_smile:
I did a file transfer test between the router and my laptop: 1Go file in 30s

Then you need to investigate why you only have 40 MBit on iperf.
Are you sure you disabled wireless on the Vero?

15

Yes the wireless module was disabled when I was connected on wired.

I just did a new test (wireless only this time)
We can already see a big difference between income/outcome … which looks already super weird for me. I should get same performances in both ways

Can you connect the Vero wired again, do a iperf3 test and upload logs via MyOSMC. Something is surely odd here.
Can you also for testing connect the notebook wired?
Also do you have any other device you can test from with iperf3?

17

SFTP is slow and has a lot of overhead.

I’m actually surprised that it’s even that fast.

Use FTP or SMB for better performance.

18

Well it doesn’t change the fact that the iperf is also so bad

Ok, I will try to see if I could do those tests

Can you post some logs so we can check for any anomalies there?
