Saurabh Gupta, our performance Program Manager, published a white paper a few months ago. It provides some performance comparisons between WCF and other existing .NET distributed computing technologies:

The technologies compared are:

  • ASP.NET Web Services (ASMX)
  • Web Services Enhancements (WSE)
  • .NET Enterprise Services (ES)
  • .NET Remoting

Different transports and settings are used in the comparisons, which show how WCF performs in different dimensions.

 

Marc Mezquita, our performance tester, published the white paper for Windows Workflow performance a year ago at:

I will publish code samples used for the performance tests used by these whitepapers on this blog soon.
