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 They also circumvent the numa architecture, because "too little bandwidth" and "too much overhead" for their usecase. Look for their eurobsdcon talks of the past years, where they thoroughly explain their designs (eurobsdcon has a yt channel with the collection of the talks)
