Architecture Question:

Auto Event Wire up is an attribute in Page directive. It is a Boolean attribute, which indicates whether the asp.net pages events are auto-wired. When we set the value of the Auto Event Wire up attribute to true, the ASP.NET runtime does not require events to specify event handlers like Page_Load or Page_Init.If we set the value of this attribute to true, framework must make a call to relate Delegate method for every Web Form (.aspx page). Therefore, it will be a performance issue and should not set the value to true if performance is a key issue.
