Lol, wait, HTTP2 and HTTP1.1 both trounce HTTP3? Talk about burying the lede. Wasn't performance the whole point behind HTTP3? This chart shows that HTTP2 is more than half as slow as HTTP1.1, and HTTP3 is half as slow as HTTP2. Jesus christ. If these get adopted across the whole web, the whole web's performance could get up to 75% slower . That's insane. There should be giant red flags on these protocols that say "warning: slows down the internet" |

The benchmark meant to compare how resource efficient the new backend for curl is by using localhost connectivity. By using localhost connectivity any real world network considerations (such as throughput discovery, loss, latency, jitter, or buffering) are sidestepped to allow a direct measurement of how fast the backend alone is. You can't then assume those numbers have a meaningful direct extrapolation to the actual performance of the web because you don't know how the additional things the newer protocols do impact performance once you add a real network. Ingoring that, you still have to consider the notes like "Also, the HTTP/1.1 numbers are a bit unfair since they do run 50 TCP connections against the server." before making claims about HTTP2 being more than half as slow as HTTP1.1.
