Difference in time taken in iis and asp net

Introduction

When it comes to web development, the choice of programming language can have a significant on the performance of the application. In the case of ASP.NET, developers often wonder about the difference in time taken between running the application in IIS (Internet Information Services) and ASP.NET . In this article, we will explore this question and provide some examples to help clarify the concept.

Understanding ASP.NET

ASP.NET is a web development framework by Microsoft. It allows developers to build dynamic web applications and services various programming languages such as C# and Visual Basic. When an ASP.NET application is run, it can be hosted either in IIS or by using the built-in development server provided by Visual Studio.

Running ASP.NET in IIS

When an ASP.NET application is hosted in IIS, it is served by the IIS web server. IIS is a powerful and scalable web server that can handle a number of concurrent requests. When a request is made to an ASP.NET application running in IIS, IIS handles the request and passes it to the ASP.NET runtime for processing. The ASP.NET runtime then executes the necessary code and the response, which is sent back to the client.


//  1: Running ASP.NET in IIS
public class HomeController : Controller
{
    public ActionResult Index()
    {
        // Code logic goes here
        return View();
    }
}

Running ASP.NET without IIS

Alternatively, developers can also run an ASP.NET application without using IIS. In this case, the application is hosted by the built-in development server provided by Visual Studio. This development server is lightweight and is primarily used for testing and debugging purposes. When a request is made to an ASP.NET application running without IIS, the development server handles the request and passes it to the ASP.NET runtime for processing, similar to how IIS handles the request.


// Example 2: Running ASP.NET without IIS
public class HomeController : Controller
{
    public ActionResult Index()
    {
        // Code logic goes here
        return View();
    }
}

Performance Considerations

When it comes to the difference in time taken between running an ASP.NET application in IIS and without IIS, there are a few factors to consider. Firstly, IIS is a highly optimized web server that is designed to handle a large number of concurrent requests . It has features such as request queuing, caching, and load balancing, which can significantly improve the performance of an application.

On the other hand, the built-in development server provided by Visual Studio is not as optimized as IIS. It is primarily intended for development purposes and may not perform as well under heavy loads. Therefore, when testing the performance of an ASP.NET application, it is to run it in IIS to get a more accurate representation of its performance in a environment.

Conclusion

In conclusion, the difference in time taken between running an ASP.NET application in IIS and without IIS can be significant. IIS is a highly optimized web server that can handle a large number of concurrent requests efficiently. On the other hand, the built-in development server provided by Visual Studio is not as optimized and may not perform as well under heavy loads. Therefore, it is recommended to run an ASP.NET application in IIS when testing its performance in a production environment.
