AspDotNetDev28-Nov-11 7:20 AspDotNetDev28-Nov-11 7:20 FYI, this doesn't make sense: ((String)Container.DataItem)["field1"]. Here are the latest Insider stories. Have you removed unnecessary HttpModules? Otherwise, you may experience contention issues, performance problems, or possible deadlocks. http://offsethq.com/how-to/improving-pc-performance.html

Alternatively, you can read the chapter from beginning to end to gain a thorough appreciation of performance and scalability design issues. Tune the Thread Pool by Using the Formula to Reduce Contention If you have available CPU and if requests are queued, configure the ASP.NET thread pool. object item = Session["myitem"]; if(item==null) { // do something else } A common pitfall when retrieving data from session state is to not check to see if the data is null If the data is used more often than it is updated, the data is a candidate for caching. pop over to these guys

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

Avoid blocking threads. When you use a try/finally block, your resources are cleaned up in the finally block if an exception occurs, and the exception is permitted to propagate up to an appropriate handler. Avoid Per-Request Impersonation Identify and, if necessary, authorize the caller at the Web server.

Also, see "CLR and Managed Code" in Chapter 15, "Measuring .NET Application Performance." For more information about the mechanics of garbage collection and generations, see "Garbage Collection Explained" in Chapter 5, Minimizing the use of session state increases the performance of your application. Pages do not time out. How To Increase Performance Of Asp.net Web Page The control is not needed during postback processing.

View state adds overhead to each request. How To Improve Performance Of Asp.net Web Application A combination of sound architecture and design, best practice coding techniques, and optimized platform and Microsoft® .NET Framework configuration is required. Read the "ASP.NET" section of Chapter 17, "Tuning .NET Application Performance" to learn how to resolve performance issues that you identify through the use of tuning metrics. Avoid asynchronous calls unless you have additional parallel work.

How To Improve Performance Of Net Windows Application Use the following guidelines when you develop server controls: Identify the use of view state in your server controls. Tune the thread pool to reduce connections, and to avoid blocking threads because blocking threads reduce the number of available worker threads. Blocking operations.

  1. Use the following techniques to reduce the number of assemblies that are not batch compiled: Do not mix multiple languages in the same directory.
  2. The request flows through the pipeline of HttpModule objects and is then run by a single HttpHandler.
  3. However, SQL authentication requires you to store credentials in the database connection string.
  4. I would be interested to see if it makes much of a difference once you have to cast the Container.DataItem and then retrieve the item versus using Eval with Reflection.
  5. It will make the performance slow.It can be avoided for most scenarios .
  6. Including HttpModules that you do not need adds extra overhead to ASP.NET request processing.
  7. Do you transfer data in chunks over I/O calls?
  8. This is a common cause of performance and scalability problems.

Do not confuse logical partitioning with physical deployment. 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 Also, your difficulty to test goes up. How To Improve The Performance Of Asp.net Mvc Web Applications For more information, see "View State" later in this chapter. Asp.net Performance Tuning Interview Questions View All Messages No new notifications.

The CPU effort is proportional to the view state size. weblink It will be stored based on the session state chosen. Evaluate your use of view state for each page. The single thread that handles an ASP.NET request is blocked from servicing additional user requests while the thread is waiting for a downstream call to return. Asp.net Performance Tuning Tools

It's more simple to optimize a stored procedure than Entity Framework. For more information, see "Deployment Considerations" later in this chapter. Your application performs I/O bound operations such as calling a Web method or accessing the file system. http://offsethq.com/how-to/improving-computer-performance.html This permits them to be cached.

Caching is particularly useful when your Web application constantly relies on data from remote resources such as databases, Web services, remote application servers, and other remote resources. Asp.net Performance Monitoring Buffering causes the server to buffer the output and send it only after it has finished the processing of the page. asked 5 years ago viewed 5097 times active 2 years ago Visit Chat Linked 2 ASP.NET Website Slow Performance on production server Related 1113A potentially dangerous Request.Form value was detected from

Minimize view state impact.

Caching data or output that is expensive to create or retrieve can reduce the costs of obtaining the data. Related: Application Development .Net Joydip Kanjilal is a Microsoft MVP in ASP.Net, as well as a speaker and author of several books and articles with more than 16 years of experience Know your application allocation pattern. Improving .net Application Performance And Scalability 2014 You can use the Response.Flush method.

Also, avoid holding objects across multiple requests. The second table saves several bytes simply by removing the white space. When a request is received by ASP.NET, the request is handled by the HttpRuntime object. his comment is here You must consider this type of performance and balance the larger key sizes against security tradeoffs at design time.

If you move your application to a new computer, ensure that you recalculate and reconfigure the settings based on the number of CPUs in the new computer. You can improve resource utilization by effectively using pooled resources, by explicitly closing or disposing resources you open, and by using efficient string management. However, adding objects to the view state adds to the overhead. You might also consider IIS compression.

Applications that allocate memory excessively on a per-request basis consume memory and create additional work for garbage collection. a) Go to IIS and select the web site. Lists of countries, states, or zip codes are some simple examples of the type of data that you might want to cache. Use Asynchronous Controllers to implement actions that depend on external resources processing.

If you connect to Microsoft SQL Server™, you can also use SQL authentication. The main headings in this chapter help you locate the topics that interest you. By default it will be stored in the Inproc. Knowing how your pages use or render data enables you to design efficient caching strategies.

and leverge a good Repository pattern: Loading Subrecords in the Repository Pattern This will optimize data access to ensure only the data needed is loaded and when only it is needed. Note – Don’t go for blindly changing it, if your application migrated from IIS6 then there could be some dependency over it. Do you use threading and synchronization features? Page fragment caching.
