> 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

Ironically.. 2.5 Gbps is created by taking a 10GBASE-T module and effectively underclocking it. I wonder if "automatic speed selection" is around the corner with modules that automatically connect at 100Mbps to 10Gbps based on available cable quality.

My 10G modules automatically drop down to 2.5G or 1G if the cable is not good enough. There's also 5G, but I have never seen it work better than 2.5G.

Oh man. I've been off the IT floor for too long. Time to change my rhetoric, ya'll have been around the corner for a while.

Aging has it's upsides and downsides I guess.

I don’t think my 10g coppers will drop to 10m. 100m sure, but 10m rings a bell.
