Benchmarks That Don't Lie to You

A benchmark is only useful if it survives contact with real workloads. The trick is to optimize for reproducibility before bragging rights.

Benchmarks That Don't Lie to You

Teams love publishing graphs. Teams are less enthusiastic about publishing setup details, warm-cache behavior, and failure modes. Curious.

If a benchmark is going to influence architecture decisions, it needs to be legible enough that someone slightly skeptical can reproduce it without summoning a shaman.

Good Benchmark Hygiene

We prefer benchmarks that make a few things painfully obvious:

  • dataset shape
  • concurrency model
  • cache assumptions
  • error handling path
  • exact environment

If any of those are vague, the benchmark is already trying on a fake mustache.

What the Reader Actually Needs

Readers usually want to know three things:

  1. Will this hold under my workload?
  2. What tradeoff bought the speedup?
  3. Where does it break?

Answer those directly and the benchmark becomes useful instead of decorative.
