I'm guessing you dropped a zero or two on the user count

i was being pretty pessimistic because tbh i’m not entirely sure of the requirements of streaming video… i guess yeah 200-500 is pretty realistic for netflix since all their content is pre-transcoded… i kinda had in my head live transcoding here, but also i said somewhere else that netflix pre-transcodes, so yeah… just brain things :p

also added an extra zero to the wattage

absolutely right again! i had in my head the TDP eg threadripper at ~1500w - it’s 350w or lower

Hey if you were thinking live-transcode I can definitely see why you'd think around 20 clients per server for CPU transcode and I can also see where such a high wattage would come from!

Edit: fun bonus fact! Netflix offers caching servers to ISPs that they can place on their side of the interconnect to mutually reduce bandwidth costs. By memory from a teardown I saw on reddit like a decade ago, it was a pretty standard 1U single socket server (probably a supermicro whitebox if we're being real)with 4-6 HDDs to serve the media files

yeah i remember that as well! considering the bandwidth netflix takes up i’m not surprised at all! i think it’s like 15% of global internet bandwidth or something crazy?
