Load Testing & Performance

You can run load testing by simulating concurrent user traffic with k6 to test API performance under expected and extreme loads. This helps uncover system limits and ensures your application handles thousands of simultaneous users without crashing.

Performance profiling pinpoints CPU and memory usage issues in Node.js applications by analyzing runtime behavior. Using profiling utilities helps identify exact bottlenecks causing degraded response times under heavy user traffic.

Yes, k6 simulates projected user traffic to generate baseline metrics for capacity planning. You estimate future resource needs and scalability requirements by analyzing how your system performs under simulated concurrent loads.

Yes, performance profiling supports Rust applications using frameworks like actix-web and tokio. It integrates with actix-web-prom and prometheus to monitor metrics while simulating traffic to identify bottlenecks.

The best way to integrate performance monitoring into CI/CD pipelines is by automating k6 load testing scripts to execute during deployment. This continuously validates API performance and prevents regressions under simulated traffic.

Your Node.js application crashes under high traffic due to unmanaged CPU and memory usage bottlenecks. Performance profiling with heapdump identifies memory leaks and resource exhaustion causing system failures during stress.
