About
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.
