[seam-dev] Seam Startup Performance

[Jason Porter]

I've wondered about the start time of Seam 3 apps. Seems like it takes a while. 

Lincoln: you on 1.1.1.Final now?

I've also wondered if event notification could be done or is done in a multi threaded way. We start getting a lot of those first life cycle calls going to many archives and it probably starts taking a bunch of time.
