Combining Minimal API and Classic Controllers: Is it Worth the Performance Boost?

In today’s rapidly evolving software development landscape, performance optimization is crucial for enhancing user experience and application efficiency. A common inquiry among developers is whether it's feasible to combine Minimal APIs with traditional controllers in ASP.NET Core, particularly to improve performance on specific high-load endpoints. This guide will delve into this question and provide insights on the potential benefits of this approach.

The Challenge: High Load Endpoints

In many applications, certain API endpoints may experience significantly higher loads compared to others. This leads developers to ask important questions:

Is it possible to combine Minimal API with regular API endpoints?

Are there performance benefits when requests land on those high-load endpoints implemented using Minimal API?

The Solution: Can Minimal API and Classic Controllers Coexist?

Yes, It’s Possible!

The good news is that it is indeed possible to integrate Minimal APIs with classic controllers in ASP.NET Core. This flexibility allows developers to leverage the strengths of both architectures. While traditional controllers offer a familiar structure for organizing routes and handling requests, Minimal APIs provide a lightweight, streamlined way to define endpoints with minimal boilerplate code.

Why Combine Them?

Combining these two approaches can provide several benefits, especially when dealing with high-load scenarios. Here are some reasons why you might consider this dual approach:

Efficiency: Minimal APIs allow you to create simpler, faster endpoints that handle requests with less overhead.

Flexibility: You can keep your existing API structure while optimizing specific endpoints for performance.

Optimization for High Traffic: By utilizing Minimal APIs for frequently accessed endpoints, you can significantly reduce response times and server load.

Performance Benefits of Minimal APIs

Real-World Tests

According to experiences shared within the development community, such as tests conducted by Nick Chapsas, switching to Minimal APIs can result in noticeable performance improvements. Here are some points to consider:

Performance Improvement: Studies have shown that transitioning to Minimal APIs can lead to a performance increase of approximately 15%. This is particularly relevant for endpoints with high traffic.

Lightweight Request Handling: Minimal APIs require less overhead, which allows for faster request handling and improved response times, especially under load.

Implementation Tips

If you decide to implement a combination of Minimal APIs and classic controllers, keep these best practices in mind:

Identify High-Traffic Endpoints: Determine which endpoints are under the most load and would benefit from being converted into Minimal APIs.

Maintain Existing Logic: Ensure that any business logic tied to your traditional controllers is integrated into the new Minimal API endpoint to avoid duplications or errors.

Test Performance: Always benchmark performance before and after the implementation of Minimal APIs to evaluate the impact accurately.

Conclusion

In conclusion, the combination of Minimal APIs and classic controllers is not only possible but can also yield significant performance benefits, particularly for endpoints that experience higher loads. By leveraging the strengths of both approaches, developers can enhance application efficiency and user experience. If you're looking to improve API performance, exploring this hybrid model may be a worthwhile endeavor.

Implementing this dual approach ensures your application rem
