Don't now if this is current because I'm using an old struts2 release
but this has helped a lot reducing my cpu & memory usage :
freemarker.template.Configuration fmc =
(freemarker
.template
.Configuration
)ServletActionContext
.getServletContext
().getAttribute(FreemarkerManager.CONFIG_SERVLET_CONTEXT_KEY);
if (fmc != null) {
((freemarker
.ext.beans.BeansWrapper)fmc.getObjectWrapper()).setUseCache(true);
}

Some where down the line Struts 2 tag are very cpu hungry , to
