Original: BenchmarkDotNet Measures Performance—But Who Enforces the Budget?

Short summary

BenchmarkDotNet measures .NET performance well but doesn't enforce budgets—you need committed baselines, threshold policies, and CI pass/fail exit codes to catch regressions automatically. The author discovered a 28% regression while dogfooding their own tool, illustrating why eyeballing CI logs fails. They announce Cedar.BenchmarkGate v0.1.0-alpha.1, an open-source tool designed to turn benchmark measurements into enforced CI gates.
