Can you describe a time when you had to optimize a FastAPI application for performance, and what steps you took to achieve that?

In a recent project, we noticed high response times under load. I implemented asynchronous endpoints, used caching for frequently accessed data, and optimized database queries using SQLAlchemy to reduce the…

🏷️
What strategies would you use to optimize the performance of a C# application that is experiencing slow response times?

To optimize a slow C# application, I would profile the application to identify bottlenecks, optimize data structures and algorithms, and leverage asynchronous programming where applicable. Additionally, I would consider caching…
