    <p>As inidicated in the comments above, I am working with OpenEJB (TomEE) committers to resolve this issue. Personally, I feel the issue is possibly due to the following:</p> <ol> <li>CDI managed beans defined and referenced in the app</li> <li>Possible CDI cyclic references (which will possibly be resolved in CDI 1.1)</li> <li>A really large CDI @SessionScoped bean, which references/injects many other CDI beans to accomplish business logic (or tasks) within the app</li> <li>TomEE/OpenWebBeans (which is still under development)</li> </ol> <p>So, the answer remains to be determined. I opened the following OpenEJB JIRA for this issue (URL below). Feel free to watch this JIRA, if interested.</p> <p><a href="https://issues.apache.org/jira/browse/OPENEJB-1955" rel="nofollow">TomEE 1.5.1 SNAPSHOT (and CDI beans) running slow on my production server</a></p> <p>UPDATE:</p> <p>Now, TomEE/CDI-managed-beans is performing just as well as Glassfish/JSF-managed-beans on the production server, because I recently did the following:</p> <ol> <li>replace frequently-used dynamic SQL with @entity named queries</li> <li>added query hints to JPA createQuery() and createNamedQuery()</li> <li>replaced frequently-used rendered="#{EL expression}" with new facelets and ui:include src="#{EL expression}", since TomEE committers advised that rendered="#{EL expression}" gets called 6 times.</li> </ol> <p>So, my TomEE/CDI-managed-beans is now running on production server and I'm monitoring performance and enduser reports/experience.</p>

    1. COmost times it's a problem with the Scopes. Did you really use CDI Scpes on that beans? Or did you just remove the javax.faces.bean.ManagedBean, making them effectively treated as @Dependent for CDI and thus they get created over and over again for each EL access? To give you some ideas: I'm serving up to 5 million page hits/day with this stack and have response times of 5 to 25 ms for average pages...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
