Just a few last words on this topic. Yes, we recently changed some internals of PrettyFaces that could have caused performance problems. They showed up on Jetty first but I think they may also have occurred under one of the following circumstances:
The webapp has a huge amount of classes in its /WEB-INF/classes folder
PrettyFaces was configured to scan /WEB-INF/lib folder for annotations
The application loads many resources for each page (images, CSS, etc.)
However I think this should be fixed now!
