IME from the perspective of an SRE / DBRE, performance is nearly always given up (if it’s ever even considered) in favor of making things easier, and this tends to have large consequences later on.

People seem to have taken the quote, “premature optimization is the root of all evil” to mean “don’t focus on performance until you absolutely have to,” but when you push them to prove that they don’t have to, they often haven’t even profiled their code! Cloud compute – and especially K8s – has made it such that it’s expected that you simply over-provision and scale as necessary to get the throughput you need. I don’t personally see running through a profiler (ideally as part of CI) as being particularly difficult or onerous.
