The hardest part, I think, is making use of that speed. 25 GBps is about the sequential speed of a decent NVMe SSD, and much faster than anything SATA. It is also faster than what a CPU can handle for all but the most basic of processing. Working at GBytes/s speeds require serious performance considerations when coding, often involving working with assembly, SIMD, etc... Things like the TCP stack start being a bottle…

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?

The BGW350 that they give you tops out at 5Gbit on the WAN SFP interface and has one 5Gbit RJ45 LAN interface along with two gigabit interfaces.

I connected the 5Gbit to a TP-Link TLSX105 10Gbit switch which has five 10Gbit RJ45 switch ports.

Since my office is on another floor and has more stuff that needs to be hardwired, I have a TP Link TLSX1008 10Gbit switch that has eight 10Gbit switch ports.

I connected the two together and, presto, 5Gbit for everyone.

My Macs have OWC 10Gbit Thunderbolt NICs so they can each get the full 5Gbit.

I tried using a Mikrotik CRS switch/router thing, but dealing with SFP inconsistencies is annoying as hell and it was a very slow router. (You need the higher end CCR routers to get 10Gbit routing, but I just wanted to have all of my devices use the Pi-Hole for DNS, which I could do with DHCP.)

UDM Pro USW-Pro-Aggregation USW-Pro-48-PoE US-XG-6PoE Recently bypassed AT&T's residential gateway by getting a XGS-PON on a SFP+ stick, let me shave off 2ms and gain a couple hundred mbps each way, in addition to removing their crappy gateway.

I thought it wasn't possible to bypass the BGW due to certs?

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)…

Unless you are say say pro competitive gamer (lag) or doing sone fringe science, anything above 1gbs real speed is useless these days. I have it, or slightly below, with pings around 7ms, and... as a regular user with some modest 10tb movies and games collection, 99% of the cases 100mbit is more than fine, and the rest covers rest. No place for anxious ocd types, but low ping and overall reliability of the connection…

True, but in my case, reliability and even price (per month) of going to 10 Gbps vs. 25 Gbps is the same.

And what I see as a use case - is when multiple people in my household would do heavy downloads simultaneously. Also, I hope I will get better-downloading speed (Steam, GoG, etc.) as with modern games, it becomes more critical, and I'll be keener to play and remove a game if I want to put in on pause, compared to keeping 3-4 100+ GB games installed at the same time.

This is the XGS-PON bypass, GPON bypass is different and 802.1x (cert) based. XGS-PON just requires cloning the serial number and MAC of the RG.

Regarding the money aspects of the high cost of entry - you can source cheap hardware from secondary markets. I just helped a friend setup a cheap selfhosting/homelab for his home. He bought couple of HP EliteDesk 800 G4 minis for $99/each with i5-8500T CPUs. Each came with 16gb ram. Both units had NVMe drives. So we just had to add couple of 2.5 SSDs 2tb ($50/each) for media storage. Running Ubuntu server with CasaO…

Where'd you find those, ebay? That sounds like a great deal.

Amazon Renewed. But Ebay has them as well. Often a bit cheaper on ebay. If you spend a bit more time searching.

The main application here is to force myself into solving those problems :) I have plans on what I'll do after. As with a 25 Gbps router comes a 25 Gbps home NAS, then I would want to have decent latency for packet processing and I hope all of that would force me to do something interesting :)

Honestly, for most applications at home, I struggle to justify even 1 Gbit/s. At my location, I have the option to upgrade to a 1 Gbit/s connection at the click of a button. I currently get 500/500 Mbit/s for ~45€ per month. 1 Gbit/s would cost around 100€ per month.

I often think about how I could justify the increase in price for myself, but I always come to the conclusion that I just don't need it. And I am a heavy internet user. I download a lot, and I upload a lot (which is why I'm very grateful for my 500 Mbit/s in upload speed). But even with "just" 500 Mbit/s, downloading a 100 GB game takes about 30 minutes. And that's provided I have an endpoint available that can supply the full 500 Mbit/s, which is surprisingly often not the case.

If I happen to need 100 GB of data, I can wait 30 minutes.

Disclaimer: I'm talking about uplink here. Internally, between my PCs, my home server and my NAS, I'm currently looking into getting 10 Gbit/s set up. And yes, I'm sure there are some use cases out there that benefit from 1 Gbit/s uplink. But I, as a power internet user, have decided for myself that I just don't need it, which means that the average Joe definitely doesn't need it.

Still, I think it's great that it's available here and I'm all for getting that expanded further.

I have been on 7Mbps / 1Mbps until 2021. Moved in with GF, she had 100Mbps ADSL which blew my mind. Now we have 2.5Gbps FTTH and I feel blessed. I'm moving to a slightly remote place soon which has 200Mbps FWA, and still it blows my mind. I can't imagine having 25Gbps at home. Insane. Downloads matter up to an extent. What still gives me day 1 shivers is 600Mbps upload after years at 1, and sub-10ms latency.

At some point in my life, I was forced to use 7/0.7 Mbps ADSL after having 50/50 Mbps and that ADSL was very oversubscribed (high packet loss and huge speed drops to Since then, I have tried to be in control of network hardware, and I now avoid *DSL, even though VDSL is decent nowadays. But the reason for 25 Gbps for me is "just because", as ISP charges the same monthly amount as I pay now (there is a setup fee for 25, though).
