Improving Net Application Performance


Open shared resources just before you need them and release them as soon as you are finished. Knowing how your pages use or render data enables you to design efficient caching strategies. Reduce Round Trips Use the following techniques and features in ASP.NET to minimize the number of round trips between a Web server and a browser, and between a Web server and Consider minIoThreads and minWorkerThreads for burst load. have a peek at this web-site

Consider using the OneWay attribute on Web methods or remote object methods if you do not need a response. For example, this might include disk I/O bound or network I/O bound operations such as reading or writing files, or making calls to another Web method. Check your Web.config file and ensure debug is set to false in the section and check your .aspx pages to ensure debug is set to false. This will reduce the additional overhead to the server.The plug-in software helps to disable the coding in the client browser.

How To Improve The Performance Of Asp.net Mvc Web Applications

Use efficient caching strategies. Alternatives to server controls include simple rendering, HTML elements, inline Response.Write calls, and raw inline angle brackets (<% %>). The following guidelines relate to the development of individual .aspx and .ascx Web page files. Is buffering disabled?

  1. View All Comments No new messages.
  2. This guide provides processes and actionable steps for modeling performance, measuring, testing, and tuning your applications.
  3. The following occurs if the formula has worked: CPU utilization increases.
  4. More Information For more information, see "Finalize and Dispose Guidelines" in Chapter 5, "Improving Managed Code Performance." Also, see "Explicitly Close Connections" in Chapter 12, "Improving ADO.NET Performance." Do Not Cache
  5. You can use the Response.Flush method.

Analyze and apply appropriate state management techniques. Design with performance in mind. Large page sizes place increased load on the CPU because of increased processing and a significant increase in network bandwidth utilization, which may lead to network congestion. How To Increase Performance Of Asp.net Web Page For these reasons, it is best to use a single trusted identity to connect to downstream databases.

Obtain resources late and release them early. If the whole page cannot be cached, can portions of it be cached? This would save you around 20 bytes of the page size.Caching is another state management technique available for you -- use it judiciously to store relatively stale data in memory. https://msdn.microsoft.com/en-us/library/ff647787.aspx This setting controls the maximum number of I/O threads in the .NET thread pool.

Avoid unnecessary exceptions. How To Improve Performance Of Net Windows Application The control is displaying read-only data. The more data you send over the network, the more bandwidth you consume. Have you removed unnecessary HttpModules?

How To Improve Performance Of Asp.net Web Application

Use ThreadsThreads are an important mechanism in programming to utilize the system resources effectively. http://www.infragistics.com/community/blogs/devtoolsguy/archive/2015/08/07/12-tips-to-increase-the-performance-of-asp-net-application-drastically-part-1.aspx If your content does not need to be delivered in near real-time, consider output caching. How To Improve The Performance Of Asp.net Mvc Web Applications Use ADO.NET asynchronous calls for ado.net methods. Asp.net Performance Tuning Interview Questions Server controls provide a clean programming abstraction and are the recommended way to build ASP.NET applications.

Table of Contents Letter to Our Customers Foreword by Rico Mariani Foreword by Brandon Bohling Foreword by Connie U Smith Foreword by Scott Barber Introduction Performance Best Practices at a Glance More Information For more information about IIS compression, see Knowledge Base article, 322603, "HOW TO: Enable ASPX Compression in IIS," at http://support.microsoft.com/default.aspx?scid=kb;en-us;322603. You can also consider HTTP compression; however, HTTP compression affects CPU utilization. Tune the thread pool to reduce connections, and to avoid blocking threads because blocking threads reduce the number of available worker threads. Asp.net Performance Tuning Tools

For example, the following custom control produces the same output as noted earlier in the section. Resource affinity. Queue work, and then poll for completion from the client. Source When CPU or memory thresholds are exceeded, applications might be recycled or blocked until the load on the server is lower.

This section helps you understand the high-level decisions that affect implementation choices for ASP.NET code. Asp.net Performance Monitoring Note   Impersonation on its own does not cause performance issues. Ensure content updates do not cause additional assemblies to be loaded.

Know Your Application Allocation Pattern Poor memory allocation patterns may cause the garbage collector to spend most of its time collecting objects from Generation 2.

Use the design guidelines chapter to learn practices, principles, patterns, and anti-patterns that will help you to make informed choices. But it won't update the browser history. When the bandwidth between client and server is limited, as is the case when a client uses a low-speed dial-up connection, pages that carry a large view state payload can significantly Improving .net Application Performance And Scalability 2014 This number is then automatically multiplied by the number of available CPUs.

This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist. Use the overloaded Server.Transfer method Server.Transfer(String,bool) instead of Server.Transfer, Response.Redirect, and Response.End to avoid exceptions. The .NET thread pool is also self-tuning. have a peek here It's more simple to optimize a stored procedure than Entity Framework.

Your decision to encrypt and decrypt credentials when they are sent over the network costs additional processing cycles. Instead, use threads from the thread pool. This chapter addresses each of these areas. Evaluate your use of view state for each page.

Meier, Srinath Vasireddy, Ashish Babbar, John Allen and Alex Mackman Microsoft Corporation May 2004 Related Links Home Page for Improving .NET Application Performance and Scalability Chapter 5 — Improving Managed Code Read the "ASP.NET" and ".NET Framework Technologies" sections of Chapter 15, "Measuring .NET Application Performance" to learn about the key metrics that you can use to measure application performance. They were already accessing their data when putting the model together, why the hell weren't they including it in the model?

Caching user data is typically only recommended when you use specialized caches, such as the ASP.NET session state store. COM interop is generally very efficient, although many factors affect its performance. This helps you avoid heap fragmentation and reduce buffer creation time. Control names are used to generate unique HTML ID names.
