Database query optimization: Review and refactor all database interactions generated by Cursor. Common issues include N+1 query problems, missing indexes, and inefficient join patterns. Use query execution plans to identify slow operations and optimize with proper indexing, query caching, or denormalization where appropriate.
API call consolidation: Cursor often generates multiple sequential API calls that could be batched or parallelized. Implement request batching, use async/await patterns effectively, and consider caching strategies for frequently accessed external data. Teams report 30-60% performance improvements simply by consolidating redundant API calls in AI-generated code.
Resource management: Add proper connection pooling, implement timeouts, and ensure resources are released correctly. Generated code frequently lacks robust cleanup logic for database connections, file handles, and network resources, leading to memory leaks under sustained production load.
Caching strategies: Implement appropriate caching layers for computational results, database queries, and API responses. Evaluate which operations benefit from Redis, in-memory caching, or CDN distribution based on access patterns and data freshness requirements.
Code profiling workflow: Use profiling tools to identify actual bottlenecks rather than optimizing prematurely. Profile under realistic production scenarios with representative data volumes and user concurrency levels to focus optimization efforts where they provide meaningful impact.
