Benchmark Testing
Benchmark testing measures a system's performance against a known, standardized reference point — either an industry-standard benchmark or the system's own prior performance — to track whether it's getting faster, slower, or staying consistent over time. It's about comparison, not just raw measurement.
Without a benchmark to compare against, a single performance number ("this endpoint responds in 200ms") is hard to judge as good or bad on its own — benchmark testing gives that number context, either against a competitor, an industry standard, or most usefully, against the same system's own historical measurements.
Running the same benchmark automatically on every release (a form of continuous performance testing) turns performance into a trackable trend line rather than an occasional spot-check — making gradual regressions visible early, before they compound into a genuinely slow product nobody remembers used to be faster.
