Load Testing Without Being Off the Mark
summary
A practical guide to load testing that shows how to design realistic scenarios (using access logs) instead of picking user counts or tools arbitrarily. Covers avoiding hardcoded data that hides cache effects, simulating TCP/TLS and connection pooling, choosing open vs closed arrival models, and using Getling/Gatling with cloud injectors; recommends capacity, stress, endurance and smoke tests, measuring failures and percentiles with HDR histograms rather than means, and running smoke tests in CI to keep regressions under 10% failure.
