I came across this article sometime back and thought to share it around. I have often discussed this during interviews and architectural reviews and was really surprised to find how many developers and solutions architects fail to comprehend the performance hits between chatty interfaces and chunky interfaces. This is especially true for web services, I can give more examples of bad Web Services implementations with 100's of method calls running over internet or WAN's resulting is slow or badly performing applications. Some of the classic implementations are where the developer decides to decorate every function call in their business logic layer with attribute and rest is history.
