Recently moved up to 3gbps bidirectional and had a hell of a time getting 3gbps even with 10gbps network card directly into the 10gbps port on the ISP-provided modem. In addition to this, there are very few services that will actually feed you data at 3gbps. Steam - ~280MB/s (2.2gbps) Battle.net launcher - ~140MB/s (1.1gbps) 25GB Torrent with 1000+ seeders - ~70MB/s (~560mbps) 2GB iso from github - ~80MB/s (~650mbps)…

Yeah, that is also what I found. 'Just' 1gbs fiber, but downloads are often bottlenecked by the server, especially things like GitHub.

You sure it is the server and not routing?

This seems like a bonkers solution to be putting packets through a 150w CPU, especially with the price of electrity in Switzerland.

It's putting a packet through a 150w CPU like weighing a brick is using using a 500 lb scale. I.e. just because it can do that much and you're using that device doesn't mean it's the relevant number to look at. When you're not pushing things it'll be near idle wattage, when you are pushing things like mad it'll be around Overall I'd bet all of the NICs and transceivers are the majority of the power usage in a given year.

These kinds of speeds are available in Switzerland because their laws state that any fiber laid down must be usable by competitors, so that ISPs must compete on service alone. I wish we had that in other countries as well.

But then who pays for laying down the fiber? What company would want to pay that cost when others can use it?

In my case it was the city. I'm not sure if the providers pay for access or is it free (paid for by taxes).

How many hours can you saturate that 25 Gbit connection up and down before support calls you and tells you to knock it off?

In my case, init7 defines that "fair use" is 0.5 PB per month. So that is about 40 hours until they start asking questions, I guess :) I doubt I will be any close to that.

Your account seems to be shadow banned (or not enough karma?). I vouched for this comment and your other comment so other people can read it.

I just upgraded to 10GbE service from Ziply Fiber in the Seattle area:

Speedtest.net - ~9.3Gbps symmetric

iperf to Denver: ~9.3Gbps symmetric (~8 threads)

iperf to Minneapolis: ~9.3Gbps symmetric

AWS S3 Download with small files: 1.3Gbps

Usenet download: 7-9.5Gbps

Mounting my ZFS pool to an AWS instance via SMBv3 in us-west-2: 3Gbps (not clear what the limit was here)

GitHub (400MB): 1 thread 400Mbps, 16 threads: 3.3Gbps

Fedora ISO from local mirror: 1 thread: 1.4Gbps, 16 threads: 4Gbps

Will try to test Steam and such.

Grants from the government. Some places also vote to have the city or town connect with Fiber which then puts tax money aside for it. In many places it is the power companies that run fiber and they are mostly partially or fully state owned. The lagest ISP also has the state as the majority share holder.

The government doesn't pay for anything.

It's whether you want to pay through it via tax dollars or directly.

By government I mean the tax payer. The government made the decision to allocate tax payer money for such things.

As it stimulates the economy similar to how laying new train track does.

The bigger benefit of all of that bandwidth is going to be multiple users. If you work from home and have a big family, or just live with a few roommates you're going to be seeing huge quality of service improvements from one person not being able to tank the whole connection.

Not with my 800k DSL you won't.

Indeed. My cheap router, when bufferbloat mitigation is turned on (codel), maxes out its CPU at 650Mbps.
