http://witestlab.poly.edu/blog/tcp-congestion-control-basics/ WebCellular, Wi-Fi, and cable broadband networks often delay and aggregate ACKs. 1 When inflight is limited to one BDP, this results in throughput-reducing stalls. Raising ProbeBW's cwnd_gain to two allowed BBR to continue sending smoothly at the estimated delivery rate, even when ACKs are delayed by up to one RTT. This largely avoids stalls. orcus final fantasy xiv
