    <p>Our application is having issue with rendering time on various part. We have been able to pin point the performance issue with a profiler (YourKit Java Profiler) within the JSF restoreView phase (lifecycle). Since, we use a lot of components in some pages the rendering of the tree must be the source of the problem. <a href="https://stackoverflow.com/questions/7190225/jsf-view-getting-rebuild-on-each-ajax-request">Some question on stackoverflow</a> looks pretty much like what we are dealing. Also, we can see the same slow speed in dev and production.</p> <p>Some specs: </p> <ul> <li>MyFaces 2.1.7</li> <li>javax.el 2.1.0</li> </ul> <p>Profiler (CTRL+SCROLL to see details): <img src="https://i.stack.imgur.com/c978A.png" alt="enter image description here"></p> <p>We are trying to find solutions. So far, we came up with those:</p> <ul> <li>Use less composition/components (which is not that great, because we liked to make generic component).</li> <li>We could also go into JSF stateless mode.</li> <li>Find the actual problem with JSF (IN DEEP).</li> <li>Recently, we found out that some JUEL library (expression language) could greatly <a href="http://forum.primefaces.org/viewtopic.php?f=3&amp;t=7453" rel="nofollow noreferrer">increase the rendering time</a>. </li> </ul> <p>I've been dealing with making JUEL works with Spring 3 (with OSGI). Here's the spec: <a href="http://mvnrepository.com/artifact/org.apache.servicemix.bundles/org.apache.servicemix.bundles.juel/2.1.3_1" rel="nofollow noreferrer">JUEL 2.1.3.1 bundle</a> (note: this bundle use a different version of javax.el than the one I use in my application will that cause clash?)</p> <p>I have found another maven repo which only does <a href="http://mvnrepository.com/artifact/de.odysseus.juel/juel-impl/2.2.6" rel="nofollow noreferrer">Juel Implementation and a more recent version</a>.</p> <p><strong>Update:</strong> Found a solution for javax.el clashing, since there was a lot of problems in the juel-api (because it's export his own javax.el) I modified the manifest with that line <strong><em>Fragment-Host: javax.el</em></strong> to eliminate it.</p> <p>Is there a configuration/set up to enable better performance? Or, how to you actually configure JUEL with MyFaces and Spring?</p>

    1. COCould you post a basic example of a JSF page / managed bean that generates this problem?

    2. COWhich implementation of JSF do you use (Mojarra or Myfaces)? Is CPU used a lot or not during the slow responses? Is the JSF in development or production mode? (development mode is really-really slow as it does much more job during a request to be able to generate nicer messages).

    3. CO@Luiggi Mendoza : Unfortunatelly, it's not really something that I can "pin point" in the code since it's pretty big. I'll look how I can reproduce this on a lower scale.

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.
