Performance Audit Standard

Methodology for identifying and fixing performance bottlenecks.

Audit Process

Step 1: Identify Hot Paths

Find code that runs frequently or processes large datasets:

• Request handlers (every HTTP request)
• Event processors (every WebSocket message)
• Loop bodies processing collections (per-item)
• Interval timers (every N seconds)
• Middleware/interceptors (every request)

Ask: "How many times per second does this code execute?" and "What's the typical input size?"

Step 2: Analyze Complexity
