What problem does it solve?

This Skill addresses the critical need to ensure applications and services can handle expected user loads and perform optimally under stress, preventing performance degradation and downtime.

Core Features & Use Cases

• Test Design & Execution: Create and run load, stress, soak, and spike tests using tools like k6, JMeter, Gatling, and Artillery.
• Bottleneck Analysis: Identify and resolve performance bottlenecks in applications, databases, and infrastructure.
• CI/CD Integration: Implement performance gates in CI pipelines to catch regressions early.
• Use Case: Before launching a new feature, use this Skill to simulate 10,000 concurrent users to ensure the system remains responsive and stable, and to identify any potential memory leaks during a 4-hour soak test.

Quick Start

Design a load test scenario for the API endpoint '/api/v1/users' using k6, targeting 500 virtual users over 5 minutes with a P95 latency threshold of 800ms.
