I fired up tcpdump on my LAN today to troubleshoot another network problem ran into this issue. The frequency of multicast udp port 3838 packets generated by BitTorrent sync clients IS INSANE. Once a minute would be more reasonable, this eight broadcast packets per second nonsense fills my captures with junk and is highly annoying. I'd like the BitTorrent developers to share the thought process behind this decision with the end users. Help us understand.
