> Wasn't performance the whole point behind HTTP3?

Faster, more secure, and more reliable, yes. The numbers in this article looks terrible, but real-world testing¹ shows that real-world HTTP/3 performance is quite good, even though implementations are relatively young.

"…we saw substantially higher throughput on HTTP/3 compared to HTTP/2. For example, we saw about 69% of HTTP/3 connections reach a throughput of 5 Mbps or more […] compared to only 56% of HTTP/2 connections. In practice, this means that the video streams will be of a higher visual quality, and/or have fewer stalls over HTTP/3."
