GIGABIT ethernet speed issue

rajat7693 · March 16, 2020, 10:39am

Hi,

I am using Aplis iMX6 1GB IT it contains a GIGABIT ethernet port but when i am trying to transfer files(.txt) to my win10 system(1 Gpbs ethernet enabled) using windows utility tool “winscp” and CAT-6 ethernet cable the maximum speed of 11 MBps is only attained. I am expecting speed to be at least 80 to 90 MBps.

Thanks

HI @rajat7693

Could you provide the version of the hardware (including carrier board) and software of your module?
Have you done some tests using ipfer3?

Best regards,
Jaski

@jaski.tx Please help to resolve issue

I tested on my side and I could easily reach up to a speed of 402Mb/s.

@jaski.tx made few changes got same results as mentioned by you,but still copying speed does not crosses 11 MBps.Inspite of Bitrate : 408 Mbits/sec

jaski.tx · March 17, 2020, 3:24pm

What did you change?
Are you using the regular Bsp 2.8b6 image?

Best regards,
Jaski

rajat7693 · March 17, 2020, 5:53pm

@jaski.tx
I am using BSP 2.8b6 image
Apalis-iMX6_LXDE-Image 2.8b6.184 20190401

jaski.tx · March 18, 2020, 5:29am

Thanks for the Information.

Are you sure that your host features a 1GBit Ethernet?
Could you provide the details (model, OS, …) of your host?

Best regards,
Jaski

rajat7693 · March 18, 2020, 8:00am

@jaski.tx
I tried host to similar host connection and achieved 90MBps speed with same data.
I am sure my host has gigabit ethernet.

Hi @rajat7693

Thanks for the information. This looks fine.

Are you trying to copy from Apalis iMX6 to your host or vice-versa?
Is the transfer speed in both directions the same?

Best regards,
Jaski

rajat7693 · March 19, 2020, 7:12am

@jaski.tx I am trying copy from Apalis iMX6 to host machine
Yes , transfer speed in both directions the same.
Tried FIlezilla and scp but results are same(max 11MBps)

rajat7693 · March 19, 2020, 4:21pm

@jaski.tx i am in a desperate need for help.

alex.tx · March 19, 2020, 9:58pm

Could you please provide more information?

You said " made few changes got same results as mentioned by you" What did you change ?
What exactly command line you are using to copy files?
Can you connect another desktop or laptop instead of Apalis and run a tests?
Are you connected through network switch?
Did you try to use another switch and network cables?

rajat7693 · March 20, 2020, 10:38am

@alex.tx

“made few changes” i followed the article Gigabit performance on Apalis iMX6Q - Technical Support - Toradex Community and used command ethtool -A eth0 rx on tx on and got result as mentioned above
i am using mRemoteNG to ssh my Aplis iMX6 and using SCP command to copy files to my remote system
I also tried different systems with gigabit ethernet and got copying result over 90Mbps with same files(two windows system)
I tried with and without network switch (b/w windows host and Aplis).And in actual scenario i can not use switch between host and Aplis
Tried 2 diff cables CAT 5E ,6
also tried using DHCP server when connecting directly(No switch)

rajat7693 · March 20, 2020, 5:01am

@alex.tx @jaski.tx i can provide a remote access for faster diagnostics as i am on time constraint.

alex.tx · March 20, 2020, 6:21pm

Could you try to copy files some different way? scp is encrypting data and it may decrease a performance.
