I have a question about TCP congestion windows. If the round trip time is highly variable, for example if there is a baseline of 30ms for most packets, but spikes every few packets to 50 or 60 ms and occasionally more, would that cause the congestion window to stay very small,limiting speeds? I believe this is what I am seeing, and it seems to make sense based on how it is calculated, but I'm not finding anyone mentioning a link between these, which makes me think I might be misunderstanding it.
