One example of using this that I have worked on recently is a WAR file that is designed to be incorporated into other applications. The build scripts for these other applications take a copy of the original WAR from SCM, and use <war update="true" ...> to customize it, by adding their own web.xml, JSP files, images, etc., while leaving the core classes and WEB-INF/lib folder unchanged. (Which is pretty much a concrete example of what you said above). I think you'll find update="true" is slower because (a) of the timestamp comparison Matt originally referred to, and (b) because you can't "replace" files in a JAR/WAR/EAR - you must create a new archive - so the existing archive must be unzipped first and a new one built with the correct files. It's probably best not to regard update="true" as a shortcut, but rather a way of refining and controlling what happens.
