I was curious: o What's the sender's qdisc configuration? o Would you be able to log periodic dumps (e.g. every 50ms or 100ms) of the test connection using a recent "ss" binary and "ss -tinm", to hopefully get a sense of buffer parameters, and whether the flow in these cases is being cwnd-limited, pacing-limited, send-buffer-limited, or receive-window-limited? o Would you be able to share a headers-only tcpdump pcap trace? thanks, neal
