One of the most common questions I get while teaching WCF is “how does WCF stack-up against the existing distributed technology stacks (ASMX, WSE, COM+, .NET Remoting) in terms of performance and throughput?” This whitepaper, written by Saurabh Gupta, offers some answers. [Via Paul Andrew]
I love the comparison between message-based security and the mixed mode where you secure the transport and use message credentials for authorization. According to this study, mixed offers 2.5x more throughput than message security (using WCF for both), and about 10x more than using WSE 2.0. I think mixed mode will end up becoming the sweet spot for many scenarios.
