Performance and High CPU utilization
There is huge performance issue and CPU hogging with Struts2 tag , this was observed while rendering JSP. These are some performance results obtained Strut 2 Tag - With all performance tuning applied as per Struts 2 documentation - Freemarker caching etc... Load Runner Tool 40 users 900 hits per second 10 transaction per second Results CPU utilization 90% Response 3.5 sec Replaced some of Struts2 Tag , with Custom JSP Tags like (s:label, s:text,s:textfield,s:hidden,s:param) 40 users 900 hits per second 15 transaction per second Results CPU utilization 70% Response 2.0 sec Some where down the line Struts 2 tag are very cpu hungry , to people to adopt to strut2 framework cpu utilization should be optimized . Did anybody come across on how to over come this problem -- View this message in context: http://www.nabble.com/Performance-and-High-CPU-utilization-tp19559123p19559123.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Performance and High CPU utilization
I have tried all the tuning parameters mentioned in the link somehow CPU utilization is always 80% ,I observed that it takes tags are rendered from free marker cache but still the cpu 80-90% .

On what plaform and JVM? How many tags are on your page? I've not seen my CPU usage anywhere near that high.

Perhaps, but if so, I'll stick with my old dev box with a P4 and 2G running WebSphere, because I don't see anything remotely approaching that kind of usage. Or the T2000's used at my last job. Same question, preferably with more info this time: what JVM, how many tags, etc. You may want to take this up with FreeMarker and/or whoever does your JVM. FreeMarker/OGNL is slow, but it's not *that* slow that it'd take up 90% CPU like that. Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Performance and High CPU utilization
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 how I suspect it is the OGNL or Freemarker rendering issue. Perhaps, but if so, I'll stick with my old dev box with a P4 and 2G running WebSphere, because I don't see anything remotely approaching that kind of usage. Or the T2000's used at my last job. Same question, preferably with more info this time: what JVM, how many tags, etc. You may want to take this up with FreeMarker and/or whoever does your JVM. FreeMarker/OGNL is slow, but it's not *that* slow that it'd take up 90% CPU like that. Dave We also need to know if you're doing anything particularly "innovative", especially in your use of OGNL. A test case (jsp+action) would be great. I've been profiling Struts2 in YourKit lately and would be happy to probe deeper if given a concrete example of the problem. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
