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.
