I do talk about variable request cost a fair bit, but I really don't think I did a good job visualising it. The rate at which each request shrinks while it's being processed by a server is meant to represent cost, but it's pretty subtle and easy to miss unless you're really watching closely. If I were to do this again, making request cost more obvious would be something I'd like to do. I had initially had requests by variable in size on screen, and moved away from that because load balancers don't typically know the cost of a request up front.
