Isn't TLP[0] supposed to fix the largest cause (tail losses) of this issue? It should result in retransmits far sooner than the 30 seconds they mention.
> Recently developed algorithms, such as BBR, model the network more accurately and optimize for latency. QUIC lets us enable BBR and update the algorithm as it evolves.
Again this is available for TCP in recent linux kernels[1]. And it's sender-side, so it should be unaffacted by ancient android devices.
Are they using ancient linux kernels on their load balancers? Or are the sysctl knobs for these features turned off in some distros?
