I have a TX2 connected at the moment (R28.2), so I’ll add results for this as well as a TX1. When running Jetson as (“tx2” is my host alias for the TX2):
iperf3 -s
…host PC as:
iperf3 -c x2 -u -b 0 -l 16k -t 120 -i 1
I see this from the TX2:
[ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams
[ 5] 0.00-120.04 sec 7.57 GBytes 542 Mbits/sec 0.201 ms 4669/496378 (0.94%)
…this from the PC:
[ ID] Interval Transfer Bitrate Jitter Lost/Total Datagrams
[ 5] 0.00-120.00 sec 7.57 GBytes 542 Mbits/sec 0.000 ms 0/496380 (0%) sender
[ 5] 0.00-120.00 sec 7.50 GBytes 537 Mbits/sec 0.201 ms 4669/496378 (0.94%) receiver
There is some packet loss, but only from the perspective of iperf3 (ifconfig did not show a loss).
Switching to TX1 (under R28.2)…
Jetson command:
iperf3 -s
PC command (“x1” is my host alias for the TX1):
iperf3 -c x1 -u -b 0 -l 16k -t 120 -i 1
This is from the TX1:
[ ID] Interval Transfer Bandwidth Jitter Lost/Total Datagrams
[ 5] 0.00-120.04 sec 7.78 GBytes 557 Mbits/sec 0.300 ms 1123/510179 (0.22%)
This is from the PC:
[ ID] Interval Transfer Bitrate Jitter Lost/Total Datagrams
[ 5] 0.00-120.00 sec 7.78 GBytes 557 Mbits/sec 0.000 ms 0/510180 (0%) sender
[ 5] 0.00-120.00 sec 7.77 GBytes 556 Mbits/sec 0.300 ms 1123/510179 (0.22%) receiver
Loss is shown in iperf3. No loss was shown from ifconfig.
Neither PC nor Jetson had any significant load going on during the test. Network is a private gigabit LAN using its own NIC and gigabit switch.
In neither case did I test the reverse direction this time since in the past this has not resulted in slow-down or loss. Let me know if you want a different test.
