Mono's new GC
I noticed that the latest Mono release has details on the new Mono GC. This is diffent to the current GC but not yet operational. It will be interesting to see bench marks against the two. I would be interested to learn more about it's impact on dynamic languages as well.
If like me your interested in this sort of thing, I found some Rotor GC notes here, here and here for you to take a look at. Also if your interested in learning more about the CLR GC in general then this Google search will get you started.
