> We (Netflix CDN) are currently bandwidth limited for serving TLS encrypted video using software ktls. (~100Gb/s on broadwell, 150-160Gb/s on skylake/cascade lake, 220Gb/s on EPYC Rome). So I'd love to have twice the bandwidth. With twice the bandwidth, I think we could probably serve 400Gb/s from a single Rome based box.
When I commented, I was assuming that people would be moving memory from RAM to the CPU to do something useful with it. If you are just dumping memory to the network, it would be more efficient to skip moving the memory to the CPU all together, or to even skip a normal CPU completely and just have network cards with a lot of RAM.
