Netflix can now serve 100Gbit/s of video (so something like 12,500 individual 4K streams) with an appliance using 100 watts of power. That’s 8 milliwatts for each 4K stream.

Remember that number the next time someone tells you that watching a Netflix show is as bad as driving an SUV or some shit.

@karppinen How the **ck can they do that ?!
I want to do the same.

Did they just have some enormous cache?!
I mean they can't do that only with SSD. It's at least 5W just for the SSD and to match 100Gb/s you need at least a good network card, RAM and CPU.

@ache @karppinen Do the maths 100 Gb/s = 12.5 GB/s, PCIe links and memory speeds of a normal PC can both keep up with that. If your software stack isn't bloated, all it has to do is fetch content from disk, encrypt it, and then send it off to the network interface. If you can use hardware AES the encryption is no problem for a normal consumer CPU.

@NohatCoder @karppinen Yes. My point is 12GB/s isn't disk speed so they have to use so sort of trick here to reduce that.

@ache @karppinen Multiple disks. You get like 5 GB/s with a good NVMe disk, so 3 of those should theoretically do.
