Man, and I thought I was cool for getting my home configured for 10 gigabits.

It wasn't too hard or expensive to get used 10 gigabit cards for my router and server. It was a bit pricier to get a used Thunderbolt 10 gigabit adapter for my Mac, but still not prohibitive.

I thought I was really future-proofing by making my house 10 gigabit compatible when I only have 2 gigabit internet, but if I have to worry about 25 gigabit internet everywhere I think I think I give up!

Earlier quoted context omitted.

Yeah but you pay for UseNet access separately. Some usenet servers charge extra for access over 100mbps or 1gbps.

Which is why you break the task into multiple threads.

Any sane Usenet client will do this by default but limitations from providers are per account not per connection.

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?

For home runs I'd recommend using duplex instead of simplex (the cable out to the provider has to stay to whatever they require of course). For a 100M cable it's $37.47 for the duplex and $24.48 for the simplex, the price difference of $13 for a really long run. The price difference of 2x 25BASE-LR (duplex) vs 2x 25BASE-BX (simplex) transceivers will be more like $60. Even if you want to stick with simplex optics eve…

True, in terms of price, duplex is cheaper (though compared to overall router cost that is negligible). In my case, I wanted to be able to swap SFPs if input one dies (for any reason), and it doesn't make a lot of sense to buy different modules for different purposes, even if that would save a bit of money.

There is another difference - if I want to go for field connectors and cut it myself, the Simplex connector would cost about 4.15$, and the Duplex would be 6.16$, which would further increase the price difference.

But thanks for the advice, it is indeed a viable option.

I've got AT&T Fiber's 5 gigabit symmetric service (with a Ubiquiti equipment stack that handles 40 gigabit without issue) and while its been very stable and I win all nerd fights with my speed tests, I've been thinking about dropping back down to 1 gigabit because I don't find much value out of 5. If it was cheaper ($180/mo for 5 gigabit) maybe I'd keep it but Astound/WaveG is offering gigabit symmetric for $50/mo wi…

What Ubiquiti equipment are you using? Doesn’t their router top out at 3.5Gbps?

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)…

Not sure what you see, but I always multiply transfers times 10 to estimate bandwidth, since there is some overhead in the TCP/IP protocol. So 280MB/s I would estimate being about 2.8gbps...

To convert MB/s to gb/s (MegaBytes per second to Gigabits per second) simply multiply by 8 (8 bits per byte). So 280MB/s is 2.24gbps (moving the decimal place).

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.

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

the one nice thing is copying big files to and from my work computer at 100 MB/s, but my work network is mostly 1 Gbps anyway so it wouldn't get any faster if I had faster internet...
