WCF Vs ASMX/Remoting/ES

This MSDN article provides a high-level performance comparison between Windows Communication Foundation (WCF) and existing Microsoft .NET distributed communication technologies.

This article says, WCF is 25%—50% faster than ASP.NET Web Services, and approximately 25% faster than .NET Remoting. Comparison with .NET Enterprise Service is load dependant, as in one case WCF is nearly 100% faster but in another scenario it is nearly 25% slower. For WSE 2.0/3.0 implementations, migrating them to WCF will obviously provide the most significant performance gains of almost 4x.
