My test on 2.5GbE network
iperf test shows 2.5Gbit/s, which is 2500Mbits/s, which should be 300MB/s.
Samba, speed around 130MB/s. However the speed is not stable, some times it’s around 80MB/s.
Netatalk, 180MB/s write, 240MB/s read. Excellent.
SCP, speed around 100MB/s. Some say it’s due to the cipher.
