Hi all, Doru, Stephan, Norbert, Denis and me spoke at ESUG about the non-use of Announcer in Bloc. I made some test cases in Bloc-Tests to compare performances between Announcer and BlEventRegistry. The result is that Announcer is at least 5x slower in all tested cases. Bloc has only specific needs about event dispatching, the first one is the efficiency during event propagation. It may be interesting to investigate why Announcer is slower and also what are the uncovered cases in BlEventRegistry. So, i'm interested in continuing our discussion about that. Regards, Glenn. ----- Glenn Cavarlé -- View this message in context: http://forum.world.st/About-the-non-use-of-Announcer-in-Bloc-tp4913008.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
