> We find that over fast Internet, the UDP+QUIC+HTTP/3 stack suffers a data rate reduction of up to 45.2% compared to the TCP+TLS+HTTP/2 counterpart.

Haven't read the whole paper yet, but below 600 Mbit/s is implied as being "Slow Internet" in the intro.

Internet access is only going to become faster. Switching to a slower transport just as Gigabit internet is proliferating would be a mistake, obviously.

It depends on whether it’s meaningfully slower. QUIC is pretty optimized for standard web traffic, and more specifically for high-latency networks. Most websites also don’t send enough data for throughput to be a significant issue.

I’m not sure whether it’s possible, but could you theoretically offload large file downloads to HTTP/2 to get best of both worlds?

High-latency networks are going away, too, with Cloudflare eating the web alive and all the other major clouds adding PoPs like crazy.
