Performance Domain Analysis

Analyze the codebase for performance bottlenecks and resource management.

Checks

• •Polling Intervals: Are there aggressive polling mechanisms (intervals < 3 seconds) that could be replaced with WebSockets?
• •Caching Strategy: Are expensive computations or database queries cached (e.g., Redis, SWR, TanStack Query)?
• •Large Payloads: Is the API returning more data than necessary for the current view?
• •Synchronous Operations: Are there heavy computations blocking the main execution thread?
• •Memory Management: Are event listeners or subscriptions properly cleaned up to prevent leaks?
• •Asset Optimization: Are images and other assets optimized or lazily loaded?

Finding Examples

• •PERF-001: Polling interval too aggressive (500ms).
• •PERF-002: Large JSON payload for simple dashboard view.
• •PERF-003: Missing memoization on expensive calculation.
