4K video doesn't require high bandwidth.

Indeed, a 4K video can hardly saturate 100Mbps link https://www.reddit.com/r/PleX/comments/eoa03e/psa_100_mbps_i...

I am confused, as the link appears to say the opposite.

> Conclusion:

>The majority of 4K movies (75%) I tested have bitrates over 100 Mbps and many seconds where bitrates spiked over 100 Mbps. Some have 100s of seconds where bitrate spikes over 100 Mbps, and will most certainly cause problems if played with bandwidths less than 100 Mbps on devices that don't buffer well such as the LG TV or Roku TV. To make sure you get the best experience without any buffering or transcoding on such devices, you need to make sure you have a bandwidth that exceeds at least 150 Mbps to play most 4K movies properly. Ideally, it should be higher than 200 Mbps.

It's interesting to see just how slow faster ethernet standards have been. Feels like I've had gigabit ethernet at a pretty low cost for nearly 20 years now, but faster than that has been pretty esoteric outside of the datacentre. I guess there really isn't much demand for faster than gigabit speeds even now (outside of servers?)

Does anyone know if this kind of connector works with a PCIe to M.2 adapter? i.e. I have a PCIe card with an NVMe drive connected, could this be used? My motherboard doesn't have an M.2 slot.

I don't see why not, but in that case you're better off using a 10 GbE PCIe ethernet adapter. Cheaper and no internal wiring.

A lot of that sounds pretty incredibly wasteful and I don’t think it should be something to strive for more of. Docker images are layered for a reason. If you’re having to download multi gigabyte docker layers multiple times, something has gone very wrong. Azure charges (like the other major cloud providers) by egress data. I feel bad for whoever is paying the bill for 20gbps going out. In general, people in ML shoul…

When I worked at Vercel during the days we supported Docker hosting (back when it was still ZEIT), we saw that even among many tenants on the same machine, the "layers" thing wasn't really that beneficial - we still had to fetch a ton of stuff over and over again.

So this is great in theory, but it doesn't really pan out in practice.

I have Jellyfin setup and there are times when 3ppl would watch something. My entire collection is the highest quality I can find on the net so normally a movie would be around 80-100GB.

Plus I have a service which downloads stuff for the archive team so that’s always doing some network traffic.

There is also a CI gitlab worker and that is also always doing some build with docker images from scratch.

I just wish more than 1Gbps was something that was offered and I can upgrade but so far I’m limited by my ISP with no way to upgrade. Inside my network I have 10Gbps and I have never hit that limit. It was expensive and I needed it for a now deprecated servicing.

For a moment I thought about setting up 10GbE at home, but then I realized there is no point yet because my external connection to internet is limited to 1 gigabit.

The only use internally would be central storage server. But all the new NVMe SSD's are faster than 10 gigs, so my internal network would be the bottleneck.

The next logical step would be upgrading to 100 gig network, but that is too expensive right now. I should buy more fast NVMe storage for that money.

If I could get 10 gigabit connection to internet, it would probably make more sense, but I don't see it coming that soon. And I'm paying 15€ for 1 gigabit right now, I would not be willing to pay much more for 10 gigabit connection.

On top of that, my Zabbix monitoring data shows that I rarely saturate the 1 gigabit connection to internet. Most of the time I don't need more than 10 megabits.

Yeah, I had a hell of a time trying to get our internal network to 100Gbps and was told by multiple experts I was being too ambitious. I ended up with 100Gbps between switches and 40Gbps to the servers.

Oh, and I would never actually use the copper cables with RJ45 for anything above 1 gigabit. Those ethernet cards heat up a lot, use too much energy. This would be a bad investment. Get a proper patch or optical cables and use SFP+ instead.
