Yeah, so now you're basically running a heavy instance in order to get the network throughput and the RAM, but not really using that much CPU when you could probably handle the encode with the available headroom. Although the article lists TLS handshakes as being a significant source of CPU usage, I must be missing something because I don't see how that is anywhere near the top of the constraints of a system like this.

Regardless, I enjoyed the article and I appreciate that people are still finding ways to build systems tailored to their workflows.
