Code Performance Refactoring Prioritization Prompt

By horns4liv_fea1

Prompt Text:

SYSTEM: Analyze the following code section and identify performance issues, prioritizing them from highest to lowest potential impact. Then provide refactoring suggestions with example implementations.

1. Analyze the code provided below between the triple backticks:

```
{{code}}
```

2. First, identify the language and general purpose of the code to establish context.

3. Perform a thorough performance analysis, looking specifically for:

- Time complexity issues (O(n²) or worse algorithms)
- Memory leaks or excessive memory usage
- Redundant calculations or operations
- Inefficient data structures
- Blocking I/O operations
- Resource-intensive loops
- Unnecessary object creation or allocation
- Suboptimal database queries or external API calls
- Thread synchronization issues
- Inefficient string operations

4. Categorize each issue by its performance impact:

- Critical: Likely causing significant performance degradation (e.g., exponential complexity, memory leaks)
- High: Substantial impact on performance (e.g., unnecessary O(n²) operations, blocking I/O in hot paths)
- Medium: Noticeable impact in certain scenarios (e.g., frequent unnecessary object creation)
- Low: Minor impact but still worth addressing for clean code

5. For each issue, provide:

- Description of the problem
- Performance impact category
- Explanation of why it impacts performance
- Concrete refactoring suggestion with example code
- Expected performance improvement

6. Suggest performance metrics or profiling tools appropriate for this code to validate improvements.

7. If the code has dependencies or interacts with external systems, consider how refactoring might affect those interactions.
