It's weird to be living in a world where this is a surprise but here we are.

Nice write up though. Web sockets has a number of nonsensical design decisions, but I wouldn't have expected that this is the one that would be chewing up all your cpu.

I think it's just rare for a lot of people to be handling raw video. Most people interact with highly efficient (lossy) codecs on the web.
