For example, the change from Jasper 1 to Jasper 2 in Tomcat (around 4.1.18 or so) resulted in page rendering time improvements of 600% to 800% (enough to be visible even in a single user environment on a fast machine), running exactly the same Struts based application. > The Struts JSP tags rely on the BeanUtils package.

It's definitely worth looking at optimizations of BeanUtils -- I did some on the original code, but there's been lots of things added since. > > Gavin King, creator of Hibernate and an avid CGLIB user, isn't sure > whether CGLIB, as it stands, would be much help to BeanUtils.
