Actually Faces (at least Mojarra) doesn't do any annotation scanning itself. It uses the annotations that are handed to it via the @HandlesTypes in the ServletContainerInitializer. I guess it depends on the Servlet container if this triggers explicit extra annotation scanning or not.

Faces and Pages do .tld (and in case of Faces -taglib.xml) scanning indeed which has some cost since it looks for patterns.

Kind regards,
