> 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

The main issue is switches, really. 5Gbps USB NICs are available for $30 on Amazon, or $20 on AliExpress. 10Gbps NICS are $60, so not exactly crazy expensive either.

But switches haven't really kept up. A simple unmanaged 5-port or 8-port 2.5GigE isn't too bad, but anything beyond that gets tricky. 5GigE switches don't seem to exist, and you're already paying $500 for a budget-brand 10GigE switch with basic VLAN support. You want PoE? Forget it.

The irony is that at 10Gbps fiber suddenly becomes quite attractive. A brand-new SFP+ NIC can be found for $30, with DACs only $5 (per side) and transceivers $30 or so. You can get an actually-decent switch from Mikrotik for less than $300.

Heck, you can even get brand-new dualport SFP28 NICs for $100, or as little as $25 on Ebay! Switch-wise you can get 16 ports of 25Gbps out of a $800 Mikrotik switch: not exactly cheap, but definitely within range for a very enthusiastic homelabber.

The only issue is that wiring your home for fiber is stupidly expensive, and you can't exactly use it to power access points either.

What do you mean by that? My home isnt wired for ethernet. I can buy 30m of CAT6 cable for £7, or 30m of fibre for £17. For a home use, that's a decent amount of cable, and even spending £100 on cabling will likely run cables to even the biggest of houses.

Isn't the expensive part more the assembly aspect? For Cat 6 the plugs and keystone jacks add up to a few dollars per port, and the crimper is like $20. I understand building your own fibre cables-- if you don't want to thread them through walls without the heads pre-attached, for example-- involves more sophisticated glass-fusion tools that are fairly expensive.

A rental service might help there, or a call-in service-- the 6 hours of drilling holes and pulling fibre can be done by yourself, and once it's all cut to rough length, bring out a guy who can fuse on 10 plugs in an hour for $150.

If you particularly want to use a raw spool, then yes that's an annoying cost. If you buy premade cables for an extra $5 each then it's fine.

Where are you finding them for that cheap? OP is talking about 20GBP for a run of fiber. If I look at, for instance, Ubiquiti their direct attach cables start at $13 for 0.5 meter cables.

I was looking at patch cables. Ubiquiti's start at $4.80
