Just to know, I saw this many times but without doing this and using
only "template_update_delay" in freemarker.properties, I can see many
logs like
2007-02-26 13:28:05,624 DEBUG (freemarker.cache:81) -
template/css_xhtml/form-validate.ftl[fr_FR,utf-8,parsed] cached copy not
yet stale; using cached
So do you think the log is wrong and cache is not used or has the
loading template from classpath been corrected ?

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

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). To refresh one page it
is
3-5 seconds with only one user. The profiler tells me the OGNL is the
bottleneck.
I notice that there are some complains on OGNL about the performance
already, may I know any other way to replace OGNL with anything else to
get
a faster speed? Currently the speed is not acceptable for production.
