     [ https://jira.jboss.org/jira/browse/JBSEAM-2704?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Pete Muir updated JBSEAM-2704:
------------------------------

          Summary: Document patterns which improve performance  (was: Performance during iteration (datatable, repeat) in the UI with value bindings that run through interceptors)
    Fix Version/s: 2.1.1.CR1
      Description: Umbrella issue for documenting patterns which can improve the performance of your Seam app.  (was: "Since we don't cache this, a particular backing bean might be called hundreds or thousands of times during rendering of a datatable, if a value binding has to be evaluated for each row. If the backing bean is a Seam component, injection of dependencies will occur for every call, involving potentially thousands of map lookups."

There is a discussion thread with a bit more data: http://www.seamframework.org/Community/SeamPerformanceOptimization

The issue is also recognized at the seamframework.org site itself: http://www.seamframework.org/Documentation/TuningTheSeamWebsite#H-IterationDatatableRepeatInTheUIWithValueBindingsThatRunThroughInterceptors

Since the issue it known, this JIRA report is created for better traceability.)

         Priority: Critical  (was: Major)
