> 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.

That is interesting though. 1gbit is becoming more common

It's wild that 1gbit LAN has been "standard" for so long that the internet caught up.

Meanwhile, low-end computers ship with a dozen 10+Gbit class transceivers on USB, HDMI, Displayport, pretty much any external port except for ethernet, and twice that many on the PCIe backbone. But 10Gbit ethernet is still priced like it's made from unicorn blood.

2.5Gbps is becoming pretty common and fairly affordable, though

My understanding is right around 10Gbps you start to hit limitations with the shielding/type of cable and power needed to transmit/send over Ethernet.

When I was looking to upgrade at home, I had to get expensive PoE+ injectors and splitters to power the switch in the closet (where there's no outlet) and 10Gbps SFP+ transceivers are like $10 for fiber or $40 for Ethernet. The Ethernet transceivers hit like 40-50C

40-50C? What is the brand?

Mine were over 90C, resulting in thermal shutdowns. I had to add an improvised heat exchanger to lower it down to ~70C: https://pics.archie.alex.net/share/U0G1yiWzShqOGXulwe1AetDjR...

I think 10GTek. However there were only 2 of them in the uplink ports on a 24x1Gbps switch in a server cabinet with decent airflow. They might have been getting up to 60C but I don't think they were hitting as high as you were saying. I've since replaced with a 8x10Gbps Hasivo switch so I can't check anymore.
