A lot of the pain a site like Twitter will have comes from GC (they wrote their own Ruby GC), and JRuby has a much better garbage collector over MRI and probably better than Twitter's.

It seems like something like Twitter would benefit lots from a good generational GC. Any more info on the one they wrote and how it differs from the built-in one? I'd love to learn more.
