a few weeks ago I posted the same problem with struts2 concerning poor
OGNL performance. Absolutely none of the advice given has helped. The
Application I wrote in Struts2 needs to handle and render large lists

Don't now if this is current because I'm using an old struts2 release

)ServletActionContext
.getServletContext
().getAttribute(FreemarkerManage
Are you, by any chance, trying to display a big list all at once?
