Caching in ASP.NET Core
The article details ASP.NET Core's three caching mechanisms: in-memory caching (for single-server apps), distributed caching (using Redis or SQL Server for multi-server deployments), and response caching (via middleware). It emphasizes that 60% of web app slowness comes from the database, 25% from slow API calls, and only 15% from memory/other issues. By caching data, developers can reduce database load by 80-90%. The post cites real-world examples: Amazon found that a 100ms delay causes 7% fewer conversions, and a 3-second load time loses 40% of users. Netflix reduced startup time by 70% through heavy caching. The guide includes code examples for each caching type, configuration options like cache expiration and size limits, and best practices such as avoiding cache stampedes and using cache tags for invalidation.
Caching is the most impactful performance optimization for web apps, directly reducing database load and improving user experience.
