I got a job ... true devops culture ... where I use Splunk etc. as much as I use git, I finally grok P99 and aggegrations and I don't hate it. It has been a mind opener and it is great to be data driven.

As an aside I think where I have seen bad performance it has been mostly architectural choices over O(N) stuff. These take a lot of organizational will power to fix properly as it costs money, time and egos.

When I interviewed at Facebook they asked me about O(N) performance of something. It felt like I was talking to a small child pretending to be smart. Don’t guess. If they aren’t willing to measure two things then compare those numbers performance is completely irrelevant. When that is impossible to understand it’s time to abandon the conversation and walk away.
