I don't have access to the article, but they're saying the issue is due to client side ack processing. I suspect they're testing at bandwidths far beyond what's normal for consumer applications.
They are testing at 1gbps.
This is not regular 4g speed for sure, and it's a rare 5g speed. regular 5g speed is (in the US) 40-50mbps, so, 20x slower than they are testing.
As said, i was only replying to the claim that this affects things at 4g/5g cell phone speeds, which it clearly does not, by their own data.
I have 5gbps internet at home myself.
But that is not what i was replying to. I was replying to the claim that this affects regular 4g/5g cell phone speeds. The data is clear that it does not.
and yet http1.1 runs on gigabit networks pretty well.
