Can you check by means of tcpdump, wireshark or similar wether packages are actually only hitting the air once? another simple bandwidth check: # host1: nc -l 8090 > /dev/zero # host2: dd if=/dev/zero | nc host1 8090 bidirectional version: # host1: nc -l 8090 > /dev/zero # host2: nc -l 8090 | nc host1 8090 # host1: dd if=/dev/zero | nc host2 8090 kill the last after a while with that I get very consistent 2.7 MB/s unidirectional, 1.4 MB/s bidirectional
