            Bug ID: 56614
           Summary: Add a switch to ignore annotations detection on tag
                    instances for performance reason
           Product: Tomcat 7
           Version: trunk
          Hardware: All
                OS: All

Performance issue

TagHandler instances are created in each jsp request.
If there are many tags in a jsp, it is very expensive to detect annotations for
each instance's construction,
even DefaultInstanceManager has the annotation caches.

For almost all the tags, annotations shouldn't be presented.
So we need to provide a way to disable the annotation detection on tags.
