Who it is for

For the people who own structural decisions

If you have ever said "we will profile it later", this is what later should have looked like.

It is for you if

  • You are a senior engineer, architect or CTO validating an architecture before it hardens.
  • You want to see where perceived latency actually comes from, not where you assume it does.
  • You need to know which causal paths dominate latency most often and how contention shapes responsiveness.
  • You want to test which architectural changes help before any code is written.

It is not for you if

  • You want to tune code that already exists. Use a profiler.
  • You want a dashboard that reassures you everything is fine.
  • You want generated recommendations. It does not tell you how to make a function faster.
  • You want to reason about latency without committing to explicit structure. This will feel uncomfortable; that is intentional.
