Tips for Improving API Performance in ASP.NET Core

A practical guide to improving API performance in ASP.NET Core covering six key techniques: using async/await properly to avoid thread pool blocking, implementing pagination for large datasets, using AsNoTracking() in EF Core for read-only queries, enabling Gzip/Brotli response compression, caching frequently accessed data with IMemoryCache or Redis, and avoiding overfetching with DTOs. Each tip includes concrete code examples. GitHub Copilot agent mode is also suggested as a tool to detect and refactor performance issues.
