To see what others can not... You must climb the mountain, A Introduction to Load Testing
summary
Uses k6.io to run ES6 load scripts and replay browser HARs, generates real runs (60s) that hit ~900–1,000 concurrent requests and ~1,900 RPS, and finds two event‑loop blocks of ~465ms and ~319ms (nearly 1s total). Integrates with N|Solid to capture blocking stacks without code changes, converts raw k6 output into visual reports, and demos dynamic test generation via JavaScript. The pipeline actually runs end to end, highlights react‑helmet as a blocker, and produces A/B comparisons for scaling decisions.
