Performance is often a vitally important issue in computer applications, especially in web applications receiving a large number of requests. One obvious way to improve performance is to buy faster hardware with more memory. But you can also tune your code to enhance performance in many ways, some of them significant. We’ll begin by examining some of the areas specific to ASP.NET which offer the greatest performance improvements and then examine some of the general .NET topics related to improving performance.
Several Microsofties involved with actually writing the .NET Framework used the word performant to mean that something is delivering higher performance. We can’t find the word in our dictionary, but it seems like a good word.
Correctly using the following features of ASP.NET offers the greatest performance improvements when an ASP.NET application is running.
Session state is a wonderful thing, but not all applications or pages require it. For any that do not, disable it.
Session state can be disabled for an entire application by setting
EnableSessionState attribute in the
Page directive to
false, as in:
<%@ Page Language="VB" EnableSessionState="false"%>
If a page will not be creating or modifying session variables but still needs to access them, set the session state to read-only:
<%@ Page Language="VB" EnableSessionState="ReadOnly"%>
By default, web services do not have session state enabled. They only have access to session ...
