qa-load-testing

Load and performance testing with k6 and JMeter, Lighthouse CI for Web Vitals, SLO-driven load plans, and performance budget gates. Covers tool choice and load profiles (with Gatling and Locust references), per-interaction INP budgets, flame-graph analysis, and database query-plan analysis.

What it installs

Skills (9)

  • db-query-plan-analyzer

    Use for any question or task about a slow SQL query or a database bottleneck, including how to read EXPLAIN or EXPLAIN ANALYZE output and database CPU that saturates under load. Reads plans from PostgreSQL, MySQL or SQLite, finds the main cost (sequential scans, nested loops, sort spills, missing or

  • flame-graph-analyzer

    Use for any question or task about reading a flame graph or CPU profile, including finding the hot path after a slow release or a regression traced to one commit. Reads flame graphs and profiles from py-spy, async-profiler, Go pprof or clinic.js, finds the hottest frames, tells CPU-bound from lock c

  • jmeter-load-testing

    Use when a project already uses Apache JMeter or needs JVM-native load testing: .jmx test plans with thread groups, HTTP samplers, assertions and listeners, headless jmeter -n runs, the HTML dashboard and CI gates from JTL results.

  • k6-load-testing

    Use whenever HTTP, WebSocket or gRPC load tests should be written in JavaScript with k6, or a k6 threshold passes but the system still feels slow: VU scripts with checks, stages for ramps, thresholds on p95 latency and errors as the CI gate, and how to read tail latency and coordinated omission.

  • lighthouse-perf

    Use when a web frontend needs Core Web Vitals (LCP, INP, CLS) checked on every PR, or its first performance budgets drafted. Sets up Lighthouse CI with Google's thresholds at the 75th percentile, per-route budgets by page type, resource-size budgets, report artifacts and PR comments.

  • load-testing-overview

    Use when a service needs load or performance testing and no tool, load profile or pass/fail threshold is chosen yet, or a live performance incident needs its cause found. Picks k6, JMeter, Gatling, Locust or Artillery, explains the six load profiles and percentiles, and gives a first CI gate.

  • perf-budget-gate

    Use when a deploy should be blocked by performance regressions from several tools. Combines k6, JMeter, Gatling or Locust results with Lighthouse CI Web Vitals, applies severity-aware thresholds against the main-branch baseline and returns one go/no-go with per-metric deltas.

  • slo-load-test-plan

    Use when SLOs and an endpoint list exist but nobody has decided which load tests to run, what load each carries or what counts as failure. Turns each SLO into scenarios with a load profile, workload model, pass/fail threshold and error-budget allowance, before any tool is configured.

  • web-vitals-inp-deep

    Use when a page feels slow to respond while LCP and CLS are green, or key interactions (form submit, modal open, route change) need an INP budget in CI. Breaks Interaction to Next Paint into input delay, processing and presentation, asserts per-interaction budgets in Playwright and finds long tasks.
