In addition to these findings, has anyone noticed this having an adverse effect on file transfers? I suspect what I have seen is due to my particular wireless hardware. (I didn't experiment with Ethernet connections.)
I used # sysctl net.ipv4.tcp_congestion_control=cubic to switch tcp_congestion_control from bbr to cubic. This improve file transfer speeds between my Debian testing system by roughly 100X on my LAN. Just posting a note to indicate that -- at least for some people -- this is a pretty serious bug. Thanks, JP
