Where Performance Fits in CI/CD Pipelines

Embedding performance testing into CI/CD pipelines requires choosing the right checks for the right stages. Not every performance test belongs on every commit, but some level of automated feedback should accompany your builds and releases.

Mapping Performance Checks to Pipeline Stages #

Typical strategies include running quick smoke or sanity performance tests on pull requests, more substantial load tests on nightly or pre-release builds and heavier stress or endurance tests on demand. The goal is to catch obvious regressions early while reserving resource-intensive tests for appropriate moments.

Example CI/CD performance mapping:
- PR: short k6 or JMeter smoke test on critical APIs
- Nightly: moderate load test on key journeys (checkout, login)
- Pre-release: full load and selected stress tests in a perf environment
- Quarterly: scheduled endurance and capacity tests

With a clear mapping, teams can rely on pipelines to provide continuous, appropriately scaled performance feedback.

Common Mistakes #

Mistake 1 — All-or-nothing performance automation #

This causes extremes.

❌ Wrong: Either no automated checks at all or trying to run full load tests on every change.

✅ Correct: Use a tiered approach with different depths of testing for different triggers.

Mistake 2 — Treating performance as a separate, manual project #

This delays insights.

❌ Wrong: Running ad hoc tests only before big launches.

✅ Correct: Integrate performance checks into regular CI/CD flows.
