Slow ethernet in linux

[dipole]

I'm only getting at most 40KB/s if I'm lucky. Apt-get update usually times out, one time it took 30 minutes to update. This is with both Ubuntu and Debian images, what gives? Is my board defective? I take a rasperry pi and plug it into the same ethernet cable and I'm able to get awesome speeds. At this point the pine64 is unusable for anything

Do you have the Pine64+ with 2GB?
Mine has the same problem, unless i changed the port to a fixed 100Mbit speed:

ethtool -s eth0 speed 100 autoneg off

or just reduce the speed on the router, if possible.

yes, I have the pine64+ with 2GB. I'll try your solution and hope it helps

Hi, thanks for the solution, albeit momentary, I contribute my bit to implement this solution in each start doing this,
add this line "ethtool -s eth0 speed 100 autoneg off" or this other "/ sbin / mii-tool -F 100baseTx-FD eth0" no commas in the /etc/rc.local, before "exit 0" to it works for me.
A greeting.

I hope this is only a temporary work around.  I was planning on using this as a TVHeadend server.

I'm having a problem with Ethernet speed too, but it's not nearly as severe as the OP.

I tested with iperf3 and the Pine is only getting around 450 Mbit/sec. When testing from another PC (on the same switch) I'm getting upwards of 900 Mbit/sec.

Any suggestions of things that I might need to reconfigure?

TIA!

can you kindly give me your output of ifconfig and /etc/network/interfaces? How do you obtain the ip for the Pine? Is it via DHCP? If yes can you kindly show the settings of the DHCP-server?

Thanks for supporting...

Here is the output of ifconfig:

And here is my interfaces file

Code:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

As for the DHCP server settings, I'm not really sure what you are looking for. The DHCP server is a router supplied to me by my internet provider. If there are specific settings you are looking for to help troubleshoot, let me know and I can check them on the router.

And thank YOU for supporting me! :-)

You should read the messages in this part of the thread: http://forum.pine64.org/showthread.php?t...10#pid2810

Bottom line is that you won't get max throughput with one thread, and inbound speeds are different from outbound.  My tests were all done over a direct connection with another host, no router or switch in the way, with minimal services running (e.g., no desktop).

I'm doubt dhcp has anything to do with network throughput. Once the ip address is assigned, the dhcp client will go idle for the span of the lease.

I agree, was only interested if the dhcp server gives certain options for the pine, e.g. mtu size or similar.
The config seems the same than mine and i also have the latest kernel, but my ethernet speed with GB activated is ridiculous (below 10Mbits). Iperf also shows a lot of retries with gb speed, with 100mbit its zero retries and steady rate about 95mbits....
So there must be some difference why some boards running high speed with gb lan and others just work with a port or setting 100mbits?

Thanks for the values, sem the same than mine. Hint for your original question already given in next post, thanks to him also....
