> And make no mistake, TCP head-of-line blocking is a real issue on high-loss networks like the outskirts of wi-fi and cellular networks. On high loss, and high speed networks. Think of wifi, or lte, with a very fat pipe after it. On really slow network, there is not much difference. Google's "real world" telemetry, and benchmarks shown HTTP2 as great, but it wasn't. Opening multiple TCP connections may well be cheaper than dealing with all of that.
