Announcement: DietPi for PineA64

[Fourdee]

Could someone please test iperf -t 60 -c <remoteip> -d since I am getting very bad results, inbound speed is ok, but outbound is awful?

Hi Er0l,

Seems fine for me. Tests below:

Pine A64+ 2GB <> Odroid C2 on 1Gbit network.
In previous tests against other devices, Odroid C2 can sustain 880Mbit. So Pine A64+ network bandwidth is impressive.

Code:

root@DietPi:~# iperf -c 192.168.0.140 -p 45678 -t 30 -d

What kernel are you running?

Code:

root@DietPi:~# uname -a
Linux DietPi 3.10.102-0-pine64-longsleep #7 SMP PREEMPT Fri Jun 17 21:30:48 CEST 2016 aarch64 GNU/Linux

Also, might be worth checking your connection is not in half duplex mode:

Code:

apt-get install ethtool

root@DietPi:~# ethtool eth0
Settings for eth0:
       Supported ports: [ TP MII ]
       Supported link modes:   10baseT/Half 10baseT/Full
                               100baseT/Half 100baseT/Full
                               1000baseT/Half 1000baseT/Full
       Supported pause frame use: No
       Supports auto-negotiation: Yes
       Advertised link modes:  10baseT/Half 10baseT/Full
                               100baseT/Half 100baseT/Full
                               1000baseT/Half 1000baseT/Full
       Advertised pause frame use: No
       Advertised auto-negotiation: Yes
       Speed: 1000Mb/s
       Duplex: Full
       Port: MII
       PHYAD: 0
       Transceiver: external
       Auto-negotiation: on
       Link detected: yes

Failing that, might be worth trying another network cable and different RJ45 socket on router/switch.
