MVVM vs MVC in ASP.net : Either better for busy websites?

I'm wondering about the underlying implementations of these design patterns specifically within asp.net. Is there a difference between the two models in terms of scalability of a website (i.e. as traffic increases might I regret following one or both of these design patterns)? I ask as someone once mentioned that MVC produces a 'lighter' website but I can find nothing to back this up.

If MVVM is as good as MVC why did MS release all the MV开发者_C百科C tools?

Thank you

Yes they are both adequate and will scale appropriately.

The significant difference is that MVVM lends itself to making use of the native bi-directional binding functionality within the .NET framework. MVC is prevalent within ASP.NET whereas MVVM is prevalent within SL/WPF.

Neither is right or wrong; the underlying technology is the largest factor in the decision process.
