OK guys, here to come something for you all to think about:
Could not stop thinking about longsleeps success to have about full GbE speed with my board while i'm not capable to do this.
So i used my laptop to boot via my PXE-server and start a actual linux session with it, not Win10.
ubuntu-gnome@ubuntu-gnome:~$ uname -a
Linux ubuntu-gnome 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Here i could also use a iperf and an iperf3 server for the pine64 and connect as iperf and iperf3 client also. Something interesting:
So while longsleep also only checked my board with iperf only (see http://forum.pine64.org/showthread.php?t...8#pid11838), i wonder whether he assumed the 'good' speed it shows with iperf to be fine and didn't try iperf3? @longsleep: Can you remember?
So maybe this also is part of the problem, iperf shows perfect speed and iperf3 not!
Can not test the real speed other than via iperf(3), because of the PXE-server there is no real disk on the host to copy to with the Pine as server (PXE-server is only a 100mbs machine), but at least the file (1.2GB from a samba share on the pine) copied with about 10.5MB/s, so about 100mbits, thats at least full speed for the PXE-host...
Trying to copy 3 samba-share files from the Pine to an also GbE network drive had about 13MB/s speed, so more than 100mbs, writing them back to the pine only had about 200kb/s, seems also very slow, but the disc at the pine is a SD-card, so the speed of this samba file test mainly depends on the reading/writing speed of the card!
Maybe this also helps to figure something out? Maybe the problem is caused by Win10 as client/server also? Can anybody also try to check his speeds with iperf and iperf3?

Of course the pine also was set up as server in iperf resp. iperf3 mode (iperf[3] -s).So while longsleep also only checked my board with iperf only (see http://forum.pine64.org/showthread.php?t...8#pid11838), i wonder whether he assumed the 'good' speed it shows with iperf to be fine and didn't try iperf3? @longsleep: Can you remember?
So maybe this also is part of the problem, iperf shows perfect speed and iperf3 not!

Maybe this also helps to figure something out? Maybe the problem is caused by Win10 as client/server also? Can anybody also try to check his speeds with iperf and iperf3?
Still a linux newbie with several EEE-PCs, PI's, LattePanda and some Desktops/Laptops running Win10. Now also proudly using Pine64+ 2GB and gigabit LAN
