How To Boost The Performance Of ASP.NET Website

Performance is a topic of discussion for every website owner. There is a time when each one of us ends up losing interest in a website if it does not perform well. Performance may be gauged differently by different people. Some may want the speed or response time to be quick, for some it is about the way a website delivers its products and services and for some it is about how well the website works on different screen sizes. In this article, we will discuss about how to improve the performance of ASP.NET website.

Is Your ASP.NET Framework Optimized For Performance?

Use a .NET framework that includes adequate optimizations so that you can ensure that your website gets a performance boost. Multi-Core JIT improvements and ASP.NET App Suspension are a few ways in which you can improve the performance of the website without code changes. It ensures hassle free performance and should be considered by website owners who are hoping to augment the performance of their website.

Are you using HTTP Compression?

With this algorithm you will be able to do away with unwanted space, file redundancies and warrant a cleaner output. This means that the file size is reduced and it takes lesser time to load the page.

For you to be able to take advantage of HTTP Compression, you must make sure that it is turned On so that the feature can work for you. Most of the modern browsers support this option but it is important that you configure it so that you can make this feature work.

You will find it under system.webServer in the ASP.NET web.config file. Alternatively, you can enable HTTP Compression in IIS.

Have you considered bundling and minifying static content files?

There is a chance that you may be using individual CSS files and JS files as static content. For any website to boost performance and ensure better scalability of the website, it is best to bundle and minify these files so that you can save on excessive consumption of the bandwidth when serving these files as per request.

You can use any of the third party tools available to bundle and minify the static content files. The process will improve the overall performance of your website by making the files lighter and reducing the bandwidth that may otherwise be used up in serving these files individually.

Are the images on your website optimized?

The images you use on your website play an important role in the loading speed. The ASP.NET website has an Image Optimizer which you can download to reduce the size of the image so that the images you use on your website are optimized for better website performance.

When it comes to images, there is more than one solution when we are discussing how to improve the performance of ASP.NET website. You can consider using Image Sprites which will allow you to retrieve small images in one request. It is used by many website owners who want to lower the total number of image requests sent to the hosting server.

Have you taken advantage of the Content Delivery Network?

When you use the Content Delivery Network (CDN) to host the images and script files on your website, you will be able to reduce the loading time and even decrease load on the server.

The job of a CDN is to ensure that the closest server is selected for delivering content when a user accesses your website. It involves a network of servers which are dispersed across various locations so that a website can use a server close to the client accessing the website and respond quickly.

It promises better performance and better user experience on your website.

Are you aware of the two caching options available on ASP.NET?

While caching is an impactful solution to how to improve the performance of ASP.NET website, it is not the only one. The above solutions will ensure that the performance is optimized, while caching will help you improve user experience after the first visit.

ASP.NET has Output Cache and Cache Object as the two ways of caching. When you have certain pages that are not updated very frequently, you can use output cache to cache them for a specific period of time. On the other hand, you have the opportunity to use cache object so that you can store objects that can be serialized in the memory.

Have you removed the HTTP Modules which are not used?

If you are not using a particular HTTP module, then remove those modules so that the server does not spend more time when it comes to processing requests. Anything that is not used and is present will only slow down the loading time of the website and have a detrimental effect on its performance.

Do you Dispose Objects once you have finished using them?

Once you are done with an object that you created, make sure you remove it so that it does not take up space and reduce performance. It is best to use Dispose and Finalize methods when releasing an object after it is done with. While the .NET framework provides you with Garbage Collector to help you do this task, you may not want to rely on its algorithms for reclaiming memory. It is best to do it on your own to make sure that the object is released and your page’s performance doesn’t suffer.


These are some of the best solutions for how to improve the performance of ASP.NET website. While you may think that a small change may not warrant a lot, you will be able to see a substantial difference in the performance of your website when you use all of these solutions together. The loading speed of your website will improve and user experience will also be augmented by using these solutions. As a result your website will gain traffic and your users will spend more time on your website because of better experience.
