description: Diagnosing and resolving performance bottlenecks and latency issues

Performance Debugging Skill

This skill focuses on identifying, analyzing, and resolving performance-related issues such as slow response times, CPU spikes, and UI lag.

When to use this skill

  • When the application is responding slower than SLAs allow.
  • When CPU usage is unexpectedly high.
  • When identifying database query bottlenecks (N+1 queries, missing indexes).

Guidelines

  • **Measure First:** Do not guess. Use profilers, APMs (Datadog, New Relic), and logging to find the bottleneck.
  • **Isolate the Scope:** Determine if the issue is in the frontend, network, backend, or database layer.
  • **Algorithmic Complexity:** Check for accidental O(n^2) or worse loops.
  • **Caching:** Consider if a caching layer (Redis, Memcached) can bypass the heavy computation.
