Yeah, but also, I want to know the p50 warm performance, not just the p99. Run the same query twice in a row after cold start. And then another 10 times. Then do another different set of queries and at the end of the day, or a week, still have no real idea how the system will perform in prod for your particular use case.
Benchmarking is hard, no argument from me!
Yep, I actually want to know the system has some sort of baseline performance that only hockey sticks under conditions I can monitor and control... but also the business wants to try new feature X and vendor is promising new performance for feature Y, and new patches are coming in affecting ???.
