Use Early Binding to Components

Early binding provides a noticeable performance increase for components that are used in ASP.NET pages. The actual performance hit from late-bound components depends on the amount of transferred data. However, for a component that has to marshal strings, an approximate measure of performance can be gauged from the following comparisons:

• 
  

  COM or COM+ components using late binding provide around the same level of performance as in ASP 3.0 with VBScript.



• 
  

  COM or COM+ components using early binding (for example, components wrapped with the tlbimp utility) provide around 50 percent better performance than in ASP 3.0 with VBScript.



• 
  

  Early-bound .NET components provide around three times better performance than the equivalent COM or COM+ components using late binding in ASP 3.0 with VBScript.

All the .NET objects provided by the framework, including all ASP.NET server controls, are automatically early-bound. The instantiate/destroy cycle is also very efficient under the .NET framework, and stateful components (components that cannot be pooled in Component Services or MTS) are acceptable.
