ASP.NET Core MVC vs Razor pages, Which is the faster?

Comparing the speed or performance of ASP.NET Core MVC and Razor Pages is not straightforward, as both are part of the same ASP.NET Core framework and share the same underlying infrastructure. The performance of your application will depend more on how efficiently you design and implement your code rather than whether you choose MVC or Razor Pages.

Here are some considerations for both ASP.NET Core MVC and Razor Pages:

ASP.NET Core MVC:
Controller-View Separation: MVC follows the Model-View-Controller pattern, providing a clear separation of concerns. This can lead to better code organization, especially in larger applications.

Fine-Grained Control: With MVC, you have more control over individual aspects of a request's lifecycle. This control can be advantageous for complex scenarios.

Attribute Routing: MVC supports attribute routing, providing flexibility in defining routes and actions.

Razor Pages:
Conciseness: Razor Pages are designed to be more straightforward and concise, with less ceremony. This can lead to faster development, especially for simpler applications.

Page Model: Razor Pages introduce the concept of a Page Model, which combines the logic and UI for a page in a single file. This can simplify the development process for certain scenarios.

Convention over Configuration: Razor Pages rely on conventions, reducing the need for explicit configuration in many cases.

CodeBehind:
Regarding "CodeBehind," it's important to note that this term is more commonly associated with traditional ASP.NET Web Forms rather than ASP.NET Core MVC or Razor Pages. In ASP.NET Core, the code-behind concept is not as prevalent, as both MVC controllers and Razor Pages include code within the same file or closely related files.

Performance:
In practice, the performance differences between MVC and Razor Pages are likely to be negligible for most applications. The choice between them should be based on factors such as code organization, project complexity, and developer preference.

If performance is a primary concern, consider focusing on optimizing specific aspects of your application, such as database queries, network calls, and resource usage. Additionally, use tools like profiling and performance testing to identify and address bottlenecks in your specific application.

Ultimately, both MVC and Razor Pages are part of the ASP.NET Core ecosystem, and the choice between them should align with your project's requirements and your team's expertise rather than perceived performance differences.
