How can AI assist in optimizing legacy code for better performance?

Asked on Dec 15, 2025

Answer

AI tools like GitHub Copilot and Amazon Q can assist in optimizing legacy code by suggesting refactoring techniques, identifying inefficient patterns, and recommending modern coding practices. These tools analyze existing codebases and provide suggestions to improve performance and maintainability.

Example Concept: AI coding tools can analyze legacy code to identify bottlenecks and suggest optimizations such as loop unrolling, algorithm improvements, or data structure changes. They leverage machine learning models trained on vast code repositories to recommend best practices and modernize outdated code patterns.

Additional Comment:

AI tools can automate the detection of code smells and provide refactoring suggestions to improve code readability and efficiency.
They can also help in converting legacy code to use newer language features or libraries that offer better performance.
Integrating AI tools into your development workflow can significantly reduce the time spent on manual code reviews and optimizations.
