A k6 threshold failure is a signal, not a verdict. This diagnostic guide helps you decide whether the application is genuinely too slow or the test itself is miscalibrated — with ordered checks, a symptom table, and escalation criteria.
Learn when to use Gatling’s open injection (constant arrival rate) versus closed injection (fixed concurrency), see a Scala DSL example, and understand the limits and pitfalls of each model.
Learn how to configure a CSV feeder in Gatling to give each virtual user unique credentials, understand memory limits, and avoid common pitfalls.
k6 thresholds turn load test metrics into automated pass/fail criteria, and when integrated into CI they become a reliable gate for performance SLAs.
Stop relying on manual graph reviews. Learn how to use k6 thresholds to automate API SLA validation and prevent performance regressions from hitting production.
Learn how Gatling's asynchronous architecture overcomes the thread-per-user bottleneck to simulate thousands of concurrent users without crashing your injector.
Load testing real-time applications requires WebSocket support. Gatling's built-in WebSocket simulation handles bidirectional communication for chat apps, live dashboards, and collaborative tools with memory-efficient non-blocking I/O.
Learn how to encode service‑level objectives as k6 thresholds and checks so load tests automatically fail when SLOs are breached, with a minimal script, trust boundaries, operational checks, failure modes, and design‑change triggers.
Learn how to feed each virtual user unique data from a CSV and validate responses with Gatling checks so your load test reflects real‑world behavior.
