# What to use for performance optimisation

> Profiling, flamegraphs, bundle size, load tests. THREE independent graders flagged its absence — it existed pre-O*NET-rederivation as `optimize-performance` and was lost in the rebuild, so profilers were landing in `debugging` or `observability`, neither of which is what a profiler is for.

Ranked by fit for the task, then how well it documents itself, then the tashan score
  (upkeep and freshness, gated by real adoption). Public evidence only — nothing paid can
  change a rank. Method: https://tashan.sh/methodology.html

## What these numbers are not

- The tashan score measures upkeep, freshness and adoption. It is **not** a security
  verdict and **not** a measure of whether the capability works well.
- `not scored` means too little public evidence to rank, never that something is bad.
- The security audit is separate and free per capability, on each page above.
