I know Daniel looked at this at some point for Seam 2 but I don't recall any deliverables so I assume the case is still open ;-) Do you think it would be handy to have Perf4J (http://perf4j.codehaus.org/) integrated into Seam 3? It has some annotation/AOP based configuration but Weld interceptor bindings would be a good fit here. And with JSF event -> CDI event propagation, the phases could probably also be timed nicely. You could then dump the stats into an Excel sheet or use the graphing servlet provided by Perf4J for output... --- Nik
