Orange Pi Zero network speed test

Measurement was performed for Orange Pi Zero (with 512MB of RAM). It has:

Ethernet 10/100M
Wi-Fi 802.11 b/g/n

Ethernet speed test

Orange Pi to PC via Ethernet

Speed test from Orange Pi to PC via Ethernet

Start network listener on PC:

nc -l 192.168.11.10 12345 >/dev/null

Transfer 100 megabytes from Orange Pi to PC:

$ dd if=/dev/zero bs=1M count=100 | nc 192.168.11.10 12345
100+0 records in
100+0 records out
104857600 bytes (105 MB, 100 MiB) copied, 8.89301 s, 11.8 MB/s

Speed test from PC to Orange Pi via Ethernet

Start network listener on Orange Pi:

nc -l 192.168.11.1 12345 >/dev/null

Transfer 100 megabytes from PC to Orange Pi:

$ dd if=/dev/zero bs=1M count=100 | nc 192.168.11.1 12345
100+0 records in
100+0 records out
104857600 bytes (105 MB, 100 MiB) copied, 9.07551 s, 11.6 MB/s

In both cases speed pretty close to declared for Ethernet (11.8 megabyte per second = 94.4 megabit).

Wi-Fi speed test

Orange Pi to PC via Wi-Fi

Measurement is very similar to previous one for Ethernet.

Wi-Fi on Orange Pi in 802.11g mode (up to 54 megabit per second).
Orange Pi acts as Wi-Fi Access Point

Speed test from Orange Pi to PC via Wi-Fi

Transfer 100 megabytes from Orange Pi to PC:

$ dd if=/dev/zero bs=1M count=100 | nc 192.168.11.10 12345
100+0 records in
100+0 records out
104857600 bytes (105 MB, 100 MiB) copied, 42.5146 s, 2.5 MB/s

Speed test from PC to Orange Pi via Wi-Fi

Transfer 100 megabytes from PC to Orange Pi:

$ dd if=/dev/zero bs=1M count=100 | nc 192.168.11.1 12345
100+0 records in
100+0 records out
104857600 bytes (105 MB, 100 MiB) copied, 54.1733 s, 1.9 MB/s

Inbound and outbound speeds are differ:

from Orange Pi: 2.5 megabyte per second = 20 megabit
to Orange Pi: 1.9 megabyte per second = 15.2 megabit
