    text
    copied!<p>I just migrated my web app from JSF managed beans to CDI managed beans, and I specifically wanted Tomcat or TomEE Plus to be the container of choice, because of the great things I heard about 'OpenWebBeans'. After deploying, configuring, and testing the TomEE 1.5+ / CDI-managed-beans web application, Full Page Refreshes are much much slower than Glassfish 3.1.2.2 / MyFaces 2.1.9 / JSF managed beans.</p> <p>With Glassfish 3.1.2.2 / MyFaces 2.1.9 / JSF managed beans, full page refreshes only take 2 to 3 seconds.</p> <p>With TomEE 1.5+ / CDI-managed-beans, full page refreshes take 5 to 10 seconds, and maybe even more than that at times. :(</p> <p>Can you please tell me why is that?</p> <p>Yesterday, prior to deploying the TomEE 1.5+ / CDI managed beans webapplication to the production server (Windows 2003 32-bit 4GB RAM and 1TB of diskspace), I read the following, which really did not answer my/this question at all:</p> <p><a href="https://stackoverflow.com/questions/3557679/glassfish-v3-vs-tomcat-7">glassfish v3 vs tomcat 7</a></p> <p>I read that PPR is better on performance than FPR, but my session timeout/management implementation involved the following:</p> <ol> <li><p>LoginFilter (servlet filter)</p></li> <li><p>the following in h:head</p></li> </ol> <p>meta http-equiv="refresh" content="#{session.maxInactiveInterval};url=pf_viewExpired.jsf"</p> <p>Is CDI more (time) expensive than JSF managed beans, or is TomEE the container of choice for CDI? I know that JBoss (or Weld) is or has the reference implementation for CDI, so it may be best to consider JBoss/Weld.</p> <p>Prior to completing the task of migrating from JSF-managed bean to CDI-managed bean (as well as migrating from Glassfish to TomEE), I had issues starting CDI-managed-bean web app on Glassfish/Weld.</p> <p>Please answer the following questions above, and/or advise. Thanks.</p>
