Using iperf3 between rpi2 and orangepi I get around 94Mbit/s, which
is ok for the rpi2. The problem is going "outside". Downloading a
file from internet can't reach 500KB/sec on the pi and around
1,2MB/s with orange pi.  Same hardware, just changing the sd card,
linux goes more than 10MB/sec. The difference is too big and is
not the storage device nor the software. Next time someone download
a file from a known server, please take a look at the output of
ftp or wget. Maybe is just me, little gremlins screwing my arm
computers while drinking bit juice...
