"Viewstate
The remarkable mechanism that displays the information of the entry posted on the server is the view state. It is loaded from the server every time. This appears to be an optional function for end users. This must be loaded from the server, and it increases the page's size, but it will slow down the website's speed if there are many controls on the page, such as user registration. If it is no longer required, it can be turned off.
According to the criteria, EnableViewState = false must be specified. It can be specified at the control, page, and configuration levels.
Variables in the session and application should be avoided.
A session is a data storage technique that allows developers to transfer values between pages. It will be saved according to the session state selected. It will be saved in the Inproc by default. IIS is used by default under those situations. When this Session variable is used in a page that is accessed by a large number of people, it takes up more memory and adds to the IIS overhead. It will slow down the performance. For the most part, it can be avoided. We can utilise a Cross Post-back, Query string with encryption if we need to communicate information across pages. If you want to keep the data on the page, caching the object is the best option
Make use of caching
The caching technique in ASP.Net is a highly useful feature. It improves performance by obviating the need for a client/server procedure. In ASP.Net, there are three forms of caching.
If there is any static material in the entire pages, the Output cache should be used. It essentially caches the content on IIS. When a page is requested, it will be loaded from IIS right away for a set amount of time. Fragment paging can also be used to save a section of a web page.
Use CSS and Script files to their full potential.
If you have huge CSS files that are utilized across numerous pages on your site, you can divide them up and save them under alternative names depending on your needs. It will reduce the time it takes for pages to load.
Dimensions of images
The inclusion of too many photos on a website has an impact on the page's performance. The graphics take a long time to load, especially on dial-up connections. Instead of using background pictures, you can utilize CSS colors or light-weight images that can be replicated across all pages.
Round travels should be avoided
We can avoid unnecessary database hits by loading the database's unaltered content. To prevent making several trips to the database, we should use the IsPostBack function.”

“Performance is a crucial part of every web application, and there are several ways to optimize web applications in ASP.NET. Big optimizations like the ASP.NET Cache can result in higher overall performance. In contrast, the tiny optimizations make small changes to repeated codes that get called a million times, but when compounded across the total requests in a day, it can bring a vast improvement.
Here are tips to optimize web applications in ASP.NET.
Use Caching
You can use the ASP.NET caching mechanism feature to gain more performance and eliminate the client/server process. Start by getting rid of any static content in the full pages using the Output cache, which stores the content on IIS. Doing so ensures that all requested pages will be loaded instantly from the ISS for the specific period. Likewise, you can also use Fragment paging to store the part of the web page.
Refrain from storing bulk data on client-side
Storing more data on the client-side affects the web page loading speed. Data stored on the remote control gets encrypted and then stored on the client-side. Instead, leverage server-side redirects – these don’t add the extra server trip.
Use IsPostBack method
Bypass unnecessary round trips to load unchanged content in the database using the IsPostBack method. ASP control will cause a postback most of the time, but some don't unless you tell them to do so.”
