I've installed iftop (network monitoring) on my Raspberry for unrelated purposes however I've noticed that the bandwidth used for ADSBX is a factor 10-15 higher than what get send out to FA. A 60 sec period (command sudo iftop -i wlan0 -s 60 -P -t) results in - edited for privacy: 2 xxx.xxx.xxx.xxx:45828 => 106Kb 106Kb 107Kb 781KB feed.adsbexchange.com:30005 <= 4.27Kb 4.10Kb 4.06Kb 30.0KB 4 xxx.xxx.xxx.xxx:46624 => 23.1Kb 23.7Kb 24.3Kb 181KB feed.adsbexchange.com:31090 <= 4.06Kb 6.49Kb 5.63Kb 42.0KB 5 xxx.xxx.xxx.xxx:55371 => 16.5Kb 14.3Kb 12.6Kb 88.3KB grung.hou.flightaware.com:6655 <= 0b 0b 0b 0B 6 xxx.xxx.xxx.xxx:42223 => 4.10Kb 4.07Kb 4.13Kb 31.8KB grung.hou.flightaware.com:1200 <= 1.41Kb 3.41Kb 3.18Kb 26.3KB Why the big difference in traffic to both sites? What does ADSBX get that FA does not?
Absolutely nothing. FA probably using the fa client to do some compression maybe. But they also open TCL/TCK tunnels securely and you probably aren't sniffing those
Thanks James, just ran the count for 1 hour. Surprising thing is that the router side shows substantially less traffic than the Pi side. This means that accuracy is lacking & research in "what is measured" or a better tool is needed. My earlier request about the difference is therefore based on inaccurate info.
