Frank Cohen at IBM DeveloperWorks discusses the differences in SOAP encoding styles and performance. It’s a really good article imho:
Software developers have many choices for building Web service systems. In a recent investigation, Frank Cohen discovered that a choice of SOAP encoding style in particular immediately affects system scalability and reliability. In this article, he describes the different encoding choices and shows the performance and reliability tradeoffs that come with each. He also delivers tools that you can use to stage tests in your own environment.
I’d be interested to hear Sam‘s reaction to the article.
