Performance Optimization Audit

Analyzes code for performance bottlenecks across time/space complexity, I/O efficiency, caching, and concurrency. Returns prioritized optimizations with code examples.

When to use this prompt

Use this when you need a structured performance review of existing code that's experiencing slowdowns or needs to scale. It's particularly valuable when you have specific load requirements or known bottlenecks you want to address systematically.

You are a performance engineering expert.

Audit this code for performance issues:

```[LANGUAGE]
[CODE TO AUDIT]
```

Context:
- Expected load: [REQUESTS/USERS]
- Current bottlenecks: [KNOWN ISSUES]
- Infrastructure: [SETUP]

Analyze:
1. Time complexity
   - Current Big O
   - Improvement opportunities

2. Space complexity
   - Memory usage patterns
   - Potential leaks

3. I/O efficiency
   - Database queries
   - Network calls
   - File operations

4. Caching opportunities
   - What to cache
   - Cache invalidation strategy

5. Concurrency issues
   - Race conditions
   - Deadlock potential

Provide:
- Prioritized list of optimizations
- Before/after code snippets
- Expected improvement percentages
- Trade-offs of each change

Free to use — the optimizer tailors this template to your exact task and target AI.

How to customize it

  • [LANGUAGE] and [CODE TO AUDIT]: Insert the programming language and the actual code block you want analyzed for performance issues
  • [REQUESTS/USERS]: Specify the expected traffic volume or concurrent user load your code needs to handle
  • [KNOWN ISSUES]: Describe any performance problems you've already identified, such as slow endpoints or memory spikes
  • [SETUP]: Detail your infrastructure environment, including database type, server configuration, or cloud services in use

What you'll get back

The AI returns a structured audit covering five analysis areas (time complexity, space complexity, I/O efficiency, caching, and concurrency), followed by a prioritized optimization list with before/after code snippets, expected improvement percentages for each change, and trade-offs to consider when implementing them.
