Hi Zheng, Have you profiled your application? Are you sure it is OGNL that makes your application slow?
>From my experience it is not so slow. At least I have not found it too be a bottleneck in my application. Not yet :-). What is really slow in WebWork/Struts2 is jsp tags like, textfield, radio, anchor, and other which are using FreeMarker templates. If it is your case, you could make it faster, you have to extract templates out of webwork.jar (in your case probably struts.jar) and put them in, for example, WEB-INF/templates directory. There is a page on WebWork Wiki about it: http://wiki.opensymphony.com/display/WW/Performance+Tuning I am not using Struts2 yet, but I believe most of the tips will work for Struts2. One more thing that could make application slower is when resource bundles are constantly reloaded. It is good for dev but not acceptable for production. Check in struts property like: webwork.i18n.reload=false Best regards Vlad Shuai Zheng wrote: > > Dear All, > > I am using struts 2.0.6, but honestly the performance is very bad (not > need > to think about scalability), to speed to load a simple page is much slower > than pure JSP (I haven't compared with struts 1).
