Have you trieed Sun's JSF 1.2? Seam 1.3.0.A is pretty good and 1.3.0 should be out soon... You also should use facelets instead of JSPs. Tomahawk immediate="true" helps a bit too on forms where you do not need validation. Hibernate caching should be used. Reduce number of complicated EL expressions per page (cause they are evaluated using reflexion). Use AJAX, bit not over do it (for things which can be done purely on client side you should do it on client side). Use client side validation if you can. Try to find out with http://facestrace.sourceforge.net/ which phase takes longest and try to improve it. Profiling should give better picture. Reduce logging and IO. Use java StringBuilder instead of StringBuffer. Minimize string concatenation, and improve other string manipulations.
