> I guess some people around the world have quite cheap utility bills! Or they work at Google and don't really have to care. Electricity is not particularly cheap in Switzerland, but not particularly expensive either (nothing like Germany for instance). If running a home lab is your hobby, why not. There are plenty of hobbies that are a lot more expensive.

The machine's clearly massive overkill for routing. Another commenter points out it typically runs around 50w - and the OP says they're also using it as a server in this thread.

For developer like me, I'm actually considering this option, it would be great to have PC like this available for some docker stuff as well, ie. MSSQL instance for development (Azure MSSQL version that runs on M1 is shit slow to the point it's unusable for development). Maybe even some tests could be offloaded from dev machine to this one etc. Would be nice to have single place for backups, photo library etc.

The problem is running it 24x7, then a small 50w is still 438 Kwh each year. That's more than a 10% increase in yearly use for a typical two person household...

Maybe having single bulky, but efficient server means other laptops/whatnot will be used less which will cancel out and be electricity negative at the end of the year.

I'm always amazed by people who don't bat an eye on the perspective of having a home server, sucking up electricity 24/7. In this case replacing a typical router (which consumes like a lightbulb), with a full-fledged PC (probably consuming like x100 the power). I guess some people around the world have quite cheap utility bills! For me, it's either a Raspberry Pi type of power consumption, or else a server that only…

You know you could just go buy an alternator and rig yourself up your own infinite power supply. Depends on the Amps of the alternator.

FWIW: raspberry pis (the 4 series) sucks in 15w which is why it’s so bloody difficult to power them through standard USB power adapters (which go up to 12w). So, not hundreds of times more power hungry, but definitely 2-3x

Just to note that's peak power consumption. They idle between 1-4W, or if you're running a PoE HAT, 4-6W.

I can't imagine ANY reason that a private household would actually need a 10G or 25G connection unless it's doubling as a workplace and they're hosting servers. Even that seems like a temporary stop-gap situation, get some rackspace in a datacenter already! Maybe they're not selling enough 25G to their business customers and they're trying to get private users onto 25G?

Init7,OP’s isp is a non profit

No, they are a regular for profit company.

What a lot of other people don't realise: - There is no such thing as a 25gbps home router. What's currently on the market is a very serious overkill ever for 10gbps.

In terms of CPU it is not totally overkill if you're using an IPS/IDS, bare in mind you'll also be disabling most of the network card offloading in a full fledged firewall and that will ultimately result in consuming slightly more CPU cycles.

> who don't bat an eye on the perspective of having a home server, sucking up electricity 24/7. Maybe they need it? A router isn't a home server. But even if, why do you keep your power efficient router running 24/7? You could turn it off when you're not home to save even more energy. > a full-fledged PC (probably consuming like x100 the power Maybe do some research before claims like these.

> But even if, why do you keep your power efficient router running 24/7? You could turn it off when you're not home to save even more energy. You jest, but I turn off my router for the night and each time I leave home for more than a day. Not just router to be exact, everything that's connected to a power strip goes down, as I turn off all the power strips. (Not OP.)

Why not just go all in and shut off at breakers?

asus "killer nic", almost pure marketing wankery with little benefit https://www.pcgamer.com/motherboards-with-killer-network-ada...

"Application offloading" was one of the terms I tried when searching for it, and got this as a result - not the same thing, but similar: https://www.academia.edu/10225597/Putting_it_on_the_NIC_A_ca...

What is the practical consumer (or even SME) use of a 10 or 25G connection? As a consumer I’d definitely get it for the fun of it, but what is the point in reality? We’ve just launched an ISP a couple of weeks ago here in Europe. Peak bandwidth use is about 3mbps per customer, and customers will download the same amount of data regardless of their plan. I acknowledge this could be lack of imagination on my part, but…

I work from home and regularly need to download large files from work servers. Several months ago I noticed that my internal network was 100Mb/s, which was dreadful. Downloads of 500MiB files would take tens of minutes, because Tomcat would drop connections on such a slow download. And even without dropped connections it generally took a long time to download anything, and Zoom call quality was regularly degraded (I…

"Zoom call quality was regularly degraded"

It sounds like something else was dodgy on your previous network, surely Zoom cannot use up 100mb/s connection

> In fact this is a nice place to ask: how would you build a "something" that monitors the network for packets sent to powered-off machines, then somehow caches the request, powers the destination machine On, and finally lets the request continue to its target? Has this been tackled anywhere? There must be tons of people wanting a homeserver but living in places where electricity has a considerable cost...

IP protocol does not guarantee delivery. So you don't have to cache request. Just power on the machine, client will retry sending the packets until the machine is powered on and can respond. Just make sure that there's no gap between networking available and http server is still starting on.
