Just went to look at the full trace and got a; Forbidden You don't have permission to access /trace/ on this server.

Hi, I've run a profile with yourkit (nice!) on my development platform. Here is the most important evidence. I've opened three product listings and a couple of product sheet in my site. Total garbage collected : 234 MB. Of these 234 MB, 64 are produced by org.jboss.remoting.transport.socket.ServerThread.run() so they are related to communication between the business layer and the presentation layer. Most of the other (156MB) are produced by com.opensymphony.xwork2.DefaultActionInvocation.invoke() so it's something related to struts. Going down the stack trace through interceptors the "last class" is org.apache.struts2.dispatcher.StrutsResultSupport.execute (ActionInvocation) that has 146MB of generated garbage. Now the interesting part : These 146MB are divided into : 34MB generated by freemarker.template.Template.process(Object, Writer) 22MB generated by com.opensymphony.xwork2.util.OgnlValueStack.findValue(String) 10MB generated by org.eclipse.jdt.internal.compiler.Compiler.compile (ICompilationUnit[]) 7MB generated by freemarker.template.Configuration.getTemplate(String) 6MB generated by org.eclipse.jdt.internal.compiler.Compiler.<init> (INameEnvironment, IErrorHandlingPolicy, Map, ICompilerRequestor, IProblemFactory, boolean) and a few other with less then 3MB each. You can find the complete trace on http://www.andreavettori.com/trace/ trace1.html. Do they seems normal numbers ??? I also don't understand if the difference between 146 and about 90 (=34+22+10+7+6+other small) is produced by org.apache.struts2.dispatcher.StrutsResultSupport.execute (ActionInvocation). That's over 50MB! Now if someone think that this can help solve my problem and understand where is produced this garbage I can run the same profile on the production server, maybe for a couple of minutes. I'm also really interested into knowing if you guys have ever checked gc collections on your applications... I don't think I'm the only one that writes "garbage producer applications" :). Thank you and please don't leave me alone with this problem! -- Ing.
