I work for Netflix Open Connect (CDN). We've been leaders on CPU and power efficiency with things like async sendfile, kernel TLS, and more. We've had servers doing 100Gb/s in production for 4 years, while competing CDNs are just now rolling out 100Gb/s servers. I have a prototype machine right now serving 375Gb/s of TLS encrypted customer video traffic with just 32 cores.

The fastest system RAM you can get that I know of is DDR4-5000, which transfers at 40 GB/s (320 Gb/s). How can you encrypt and send data faster than your memory can even transfer it to the CPU? Or is there something I'm misunderstanding?
