> As a developer of web apps, I will personally continue to not think that much about HTTP/3. Perhaps in the future network/systems engineers will have figured out how to make it bear fruit? I don't know, but it seems to me of unclear wisdom to count on it.
Congestion control algorithm - and congestion window sizing/tuning - plays a not-insignificant role in throughput, especially when comparing a 15KiB object vs. a 1MiB object. It's often _more_ outsized for those "medium sized" objects, as too small a window won't scale up by the time the transfer completes in some cases.
In other words: this is a good post, but the caveats around congestion control algorithm are a little understated w.r.t. the benchmarks.
