Here are some ways to speed up ASP.NET applications. Some of them include:

Use caching: The easiest and fastest means of accelerating an ASP.NET application is by employing caching. For example, data, pages, or controls can be cached in order to expedite their loading processes. To cache a page for 60 seconds, one may use the following example:

protected void Page_Load(object sender, EventArgs e)

Optimize images: This results in pages being slower to load large images. To reduce their file sizes without reducing their qualities, there is an image optimization tool you can use. For example:

<img src="~/Images/MyImage.jpg?width=400" alt="My Image" />

Use a content delivery network (CDN):They share files from your website across many servers which makes it take less time for them to load. This is one way to use Microsoft Azure CDN:

<asp:ScriptManager runat="server">
        <asp:ScriptReference Path="" />

Minify CSS and JavaScript: Minification of CSS and JavaScript files makes them smaller in size thus enabling faster loading. Below is an example using Microsoft ASP.NET Web Optimization Framework:

bundles.Add(new ScriptBundle("~/bundles/jquery").Include(

bundles.Add(new StyleBundle("~/Content/css").Include(

Use asynchronous programming: With asynchronous programming, your application can do more than one activity at once, thus improving its speed as a whole. The next example illustrates this using async and await keywords:

public async Task<ActionResult> Index()
    var data = await _repository.GetDataAsync();
    return View(data);


Optimize database queries: : Queries that are processed slowly in a database can result in performance problems. Techniques to help optimize querying include the use of indexes, stored procedures and other tricks.

CREATE INDEX IX_Employee_LastName
ON Employee (LastName)

Do Profiling: a profiler may assist you in finding out where your application is underperforming. Profiling tools can be used to measure how your application performs and identify the areas that need to be enhanced.

var profiler = new dotTraceProfiler();
// Run your application and perform actions to profile

Use a faster web server: Using a faster web server like IIS or Apache will improve the performance of your application.

    <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
      <add mimeType="text/*" enabled="true" />
      <add mimeType="message/*" enabled="true" />
      <add mimeType="application/javascript" enabled="true" />
      <add mimeType="*/*" enabled="false" />
      <add mimeType="text/*" enabled="true" />
      <add mimeType="message/*" enabled="true" />
      <add mimeType="application/javascript" enabled="true" />
      <add mimeType="*/*" enabled="false" />

Use compression: Performance could be improved through the reduction of data transmitted from the server to the client.

public void Page_Load(object sender, EventArgs e)
    Response.ContentType = "text/html";
    Response.AppendHeader("Content-Encoding", "gzip");
    using (var output = new GZipStream(Response.OutputStream, CompressionMode.Compress))
        var buffer = Encoding.UTF8.GetBytes("Hello, world!");
        output.Write(buffer, 0, buffer.Length);


We recommend following some good practices and optimizing your code being able to drastically improve performance of your ASP.NET application as a company dealing with ASP.NET development. Caching; image optimization; use of CDN (content delivery network); minify CSS/JavaScript; use asynchronous programming techniques; optimize database queries; profile your code base; use faster web hosting and compressing it.
