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)
