Performance Analysis

[ajanz]

my application has bad performance.

i checked my classes, but they seem ok.

how can i check what the framework does? any hints/tools i should use?

it seems there is some problem. some request took between 1ms and 4 s. i don't know why.

I did the following to check where the time is spend:
http://seamframework.org/Community/SeamPerformanceProblemRewardingWorkaround

And I added the timingInceptor to the standard list of interceptors, so that all components are measured. This can be done by adding the following part in the components.xml:

<core:init debug="@debug@" jndi-pattern="@jndiPattern@">
<core:interceptors>
<value>org.jboss.seam.core.SynchronizationInterceptor</value>               <value>org.jboss.seam.async.AsynchronousInterceptor</value>               <value>org.jboss.seam.ejb.RemoveInterceptor</value>               <value>org.jboss.seam.persistence.HibernateSessionProxyInterceptor</value>               <value>org.jboss.seam.persistence.EntityManagerProxyInterceptor</value>               <value>org.jboss.seam.core.MethodContextInterceptor</value>               <value>org.jboss.seam.core.EventInterceptor</value>               <value>org.jboss.seam.core.ConversationalInterceptor</value>               <value>org.jboss.seam.bpm.BusinessProcessInterceptor</value>               <value>org.jboss.seam.core.ConversationInterceptor</value>               <value>org.jboss.seam.core.BijectionInterceptor</value>
<value>org.jboss.seam.transaction.RollbackInterceptor</value>               <value>org.jboss.seam.transaction.TransactionInterceptor</value>
<value>org.jboss.seam.webservice.WSSecurityInterceptor</value>               <value>org.jboss.seam.security.SecurityInterceptor</value>                              <value>TimingInterceptor</value>
</core:interceptors>
</core:init>

I hope this helps you
