Totally agreed that 100w is a waste at idle, but I don’t think that’s what the parent was talking about. My read was that the parent comment was responding to capacity planning tending towards reducing the number of servers (without building out low latency cold boot infra) in the name of cost/energy savings, and that resulting in higher latency request latency. Anecdotally this seems plausible, but I don’t have metrics to back it up.
